Organizing Microsoft Teams Assignment Submissions with PowerShell

Sun, 04 Oct 2026 00:00:00 +0000

Microsoft Teams makes collecting assignments convenient, but the folder structure obtained when the submissions are downloaded from SharePoint is not always convenient for offline marking or archiving.

A bulk download is organized primarily by student. Each student has a folder, each assignment appears as a subfolder, and the submitted file may be stored inside another folder such as Version 1.

For example:

416-2026\
├── 2100001 - Student Name\
│ ├── Assignment 1\
│ │ └── Version 1\
│ │ └── report.pdf
│ └── Assignment 2\
│ └── Version 1\
│ └── presentation.pptx
├── 2100002 - Another Student\
│ ├── Assignment 1\
│ │ └── Version 1\
│ │ └── final-report.pdf
│ └── Assignment 2\
│ └── Version 2\
│ └── slides.pptx
└── ...

This structure is useful when you want to see everything submitted by one student. However, it is cumbersome when you want to mark or review one assignment for the entire class.

A short PowerShell script can reorganize the downloaded files automatically into:

_ByAssignment\
├── Assignment 1\
│ ├── report_2100001_v1.pdf
│ ├── final-report_2100002_v1.pdf
│ └── ...
└── Assignment 2\
 ├── presentation_2100001_v1.pptx
 ├── slides_2100002_v2.pptx
 └── ...

The new filename keeps the original filename and adds:

the student ID, taken from the first seven characters of the student’s folder name; and
the submission version, such as v1, v2, etc.

The original downloaded files are left untouched.

1. Open the class Team in SharePoint

Open the relevant Class Team in Microsoft Teams.

Navigate to the Team’s files and choose Open in SharePoint. Depending on the Teams interface in use, the command may appear as View in SharePoint.

This opens the SharePoint site associated with the Team.

Note

This can also be done from the web browser version of Teams.

2. Open Site contents

Once the Team site opens in SharePoint, select Site contents.

Depending on the SharePoint layout, Site contents may be visible in the site navigation or accessible through the Settings menu.

The Site contents page lists the document libraries and other resources associated with the Team.

3. Open Student Work → Submitted Files

From Site contents, locate and open the document library named Student Work.

Inside Student Work, open Submitted Files.

The path is:

Site contents
 └── Student Work
 └── Submitted Files

Inside Submitted Files, the folders are normally organized student by student:

Submitted Files\
├── 2100001 - Student Name\
├── 2100002 - Student Name\
├── 2100003 - Student Name\
└── ...

Each student directory contains folders corresponding to that student’s assignments.

4. Download the submissions

Select the Submitted Files folder and choose Download.

SharePoint will prepare the selected contents for download, normally as a compressed archive.

Save the archive and extract it to a convenient local folder.

For example:

F:\416-2026

After extraction, the top level may look like:

F:\416-2026\
├── 2100001 - Student Name\
├── 2100002 - Student Name\
├── 2100003 - Student Name\
└── ...

A particular student submission might look like:

2100001 - Student Name\
└── EEE 416 - Project Report and Presentation Sli\
 └── Version 1\
 ├── EEE416-Jan2026-B1-G04-Final-Presentation-v9.pptx
 ├── EEE416_B1-04_Final_Project_presentation.pdf
 ├── EEE416_B1-04_Final_Project_Report (2) (1).docx
 └── EEE416_B1-04_Final_Project_Report.pdf

This is the structure that the PowerShell script will reorganize.

5. Create the PowerShell script

Open Notepad, Visual Studio Code, or another plain-text editor.

Create a file named:

Organize-Teams-Assignments.ps1

For example, save it in the downloaded course folder:

F:\416-2026\Organize-Teams-Assignments.ps1

Paste the following script into the file:

<#
.SYNOPSIS
 Reorganize downloaded Microsoft Teams / SharePoint
 student submissions by assignment.

.DESCRIPTION
 Expected source structure:

 SourceRoot\
 2100001 - Student Name\
 Assignment A\
 Version 1\
 file1.pdf
 file2.docx
 Assignment B\
 Version 2\
 file3.pptx

 Produces:

 SourceRoot\_ByAssignment\
 Assignment A\
 file1_2100001_v1.pdf
 file2_2100001_v1.docx
 Assignment B\
 file3_2100001_v2.pptx

 The student ID is taken from the first seven characters
 of the student folder name.

 The original files are copied, not moved.

6. Set the source and output folders

Near the beginning of the script are these lines:

[string]$SourceRoot = "F:\416-2026",
[string]$OutputRoot = "F:\416-2026\_ByAssignment"

Change F:\416-2026 to the directory where you extracted your own Teams submissions.

For example:

[string]$SourceRoot = "D:\Courses\EEE416\Submissions",
[string]$OutputRoot = "D:\Courses\EEE416\Submissions\_ByAssignment"

The _ByAssignment folder does not need to exist beforehand. The script creates it automatically.

7. Open PowerShell in the folder

Open the downloaded submissions folder in File Explorer.

One convenient method is:

Click the File Explorer address bar.
Type powershell.
Press Enter.

PowerShell will open with that folder as its current directory.

Alternatively, open PowerShell normally and change directories:

cd F:\416-2026

Confirm that the script is present:

dir

You should see:

Organize-Teams-Assignments.ps1

8. Run the script

Run:

.\Organize-Teams-Assignments.ps1

The script processes each student folder and displays its progress.

For example:

Student: 2100001 [2100001 - Student Name]

 EEE416-Jan2026-B1-G04-Final-Presentation-v9.pptx
 -> EEE416-Jan2026-B1-G04-Final-Presentation-v9_2100001_v1.pptx

 EEE416_B1-04_Final_Project_Report.pdf
 -> EEE416_B1-04_Final_Project_Report_2100001_v1.pdf

At the end, it displays a summary:

============================================
Processing complete.
Students processed : 52
Files copied : 187
Output folder : F:\416-2026\_ByAssignment
============================================

If PowerShell blocks the script

Some Windows systems may prevent .ps1 files from running because of the PowerShell execution policy.

To allow the script only for the current PowerShell session, run:

Set-ExecutionPolicy -Scope Process Bypass

Then run the script again:

.\Organize-Teams-Assignments.ps1

Closing that PowerShell window removes the temporary setting.

Warning

On computers managed by an organization, PowerShell execution policy may be centrally controlled. Follow your organization’s IT policy rather than changing a machine-wide execution policy.

The resulting folder structure

For this original submission:

2100001 - Student Name\
└── EEE 416 - Project Report and Presentation Sli\
 └── Version 1\
 ├── EEE416-Jan2026-B1-G04-Final-Presentation-v9.pptx
 ├── EEE416_B1-04_Final_Project_presentation.pdf
 ├── EEE416_B1-04_Final_Project_Report (2) (1).docx
 └── EEE416_B1-04_Final_Project_Report.pdf

the script creates:

_ByAssignment\
└── EEE 416 - Project Report and Presentation Sli\
 ├── EEE416-Jan2026-B1-G04-Final-Presentation-v9_2100001_v1.pptx
 ├── EEE416_B1-04_Final_Project_presentation_2100001_v1.pdf
 ├── EEE416_B1-04_Final_Project_Report (2) (1)_2100001_v1.docx
 └── EEE416_B1-04_Final_Project_Report_2100001_v1.pdf

A later submission version is labelled accordingly. For example:

2100002 - Student Name\
└── Project Report\
 └── Version 3\
 └── Final Report.pdf

becomes:

_ByAssignment\
└── Project Report\
 └── Final Report_2100002_v3.pdf

What the script does

Identifies the student

Only folders beginning with seven digits are treated as student folders:

2100001 - Student Name

The first seven characters become the student ID:

Creates one folder per assignment

The existing assignment folder names are reused automatically. There is no need to enter the assignment names separately.

Detects submission versions

Folders such as:

Version 1
Version 2
Version 3

are converted to filename suffixes:

_v1
_v2
_v3

If a file is not contained in a numbered Version folder, the script assumes version 1.

Keeps the original filename

The existing filename is retained. The student ID and submission version are inserted before the extension.

For example:

Project Report.pdf

becomes:

Project Report_2100001_v1.pdf

Keeps the original download unchanged

The script uses Copy-Item, not Move-Item.

The original SharePoint download therefore remains intact and can be retained as the untouched archive.

Prevents silent overwrites

If two files would produce exactly the same destination filename, the script does not silently replace the first file. It creates a unique filename by adding _2, _3, and so on.

Why reorganize submissions this way?

The original Teams/SharePoint directory structure effectively answers:

What did this particular student submit?

For marking and course administration, the more useful question is often:

What did everyone submit for this particular assignment?

An assignment-wise directory is convenient for:

grading reports;
reviewing presentations;
distributing submissions among multiple evaluators;
checking whether everyone submitted the required file type;
batch-opening PDF or Word files;
running automated processing over submissions;
comparing different submission versions;
archiving a completed course; and
keeping the student ID attached to a file even when it is copied elsewhere.

Before deleting anything from SharePoint

Treat this workflow as an export and reorganization process, not as an immediate replacement for the original Teams/SharePoint records.

A sensible sequence is:

Download the submissions.
Keep the original extracted download.
Run the PowerShell script.
Check the number of students and copied files.
Spot-check several assignments and submission versions.
Make any archival or SharePoint cleanup decisions only after verifying the backup.

For important course records, keeping an untouched copy of the original download is a useful precaution.

Complete workflow

Microsoft Teams
 ↓
Open/View in SharePoint
 ↓
Site contents
 ↓
Student Work
 ↓
Submitted Files
 ↓
Download
 ↓
Extract archive
 ↓
Run PowerShell script
 ↓
_ByAssignment
 ↓
One folder per assignment
with Student ID + submission version
in each filename

The result is a simple assignment-oriented archive that is much easier to review, mark, distribute, and preserve than the student-oriented structure produced by the raw SharePoint download.

Bangladeshi Currency Formatting and Amount-in-Words in Microsoft Excel

Tue, 24 Feb 2026 00:00:00 +0000

Bangladesh Crore–Lakh format · ৳ / BDT currency display · English and Bangla amount in words · No VBA

Microsoft Excel normally uses the international thousands–millions grouping system. It also does not provide a built-in function for converting a monetary amount into words.

For financial documents in Bangladesh, however, we often need numbers in forms such as:

৳ 1,99,66,612.24

and, in words:

One Crore Ninety-Nine Lakh Sixty-Six Thousand
Six Hundred and Twelve Taka and Twenty-Four Paisa Only

or in Bangla:

এক কোটি নিরানব্বই লাখ ছেষট্টি হাজার
ছয়শ বারো টাকা এবং চব্বিশ পয়সা মাত্র

This guide shows how to do all three in Excel:

Format numbers using the Bangladeshi Crore–Lakh–Thousand grouping.
Add BDT or the ৳ Taka symbol without turning the number into text.
Convert an amount into words in English.
Convert an amount into words in Bangla.

Everything is done using Excel’s built-in formatting and worksheet formulas. No VBA, macros, or add-ins are required.

1. Format Numbers in Bangladeshi Crore–Lakh Style

Excel normally displays a large number using the international grouping convention:

99,999,999.99

In Bangladesh, the same number is normally written as:

9,99,99,999.99

The grouping is:

Crore | Lakh | Thousand | Units
 9 | 99 | 99 | 999.99

Excel can display this format while keeping the underlying cell as a normal numeric value.

Where to Paste the Custom Number Format

Select the cells containing the numbers.
Press Ctrl + 1.
Select the Number tab.
Select Custom from the Category list.
Click inside the Type box.
Delete the existing format shown there.
Paste the custom format given below.
Click OK.

For numbers with two decimal places, paste:

[>9999999]0","00","00","000.00;[>99999]#0","00","000.00;#,##0.00

For example:

99999999.99

will be displayed as:

9,99,99,999.99

Similarly:

12500000.50

will appear as:

1,25,00,000.50

and:

125000.75

will appear as:

1,25,000.75

The value stored in the cell is unchanged. Therefore, functions such as SUM, multiplication, division, sorting, filtering, and references to the cell continue to work normally.

Bangladeshi Number Format Without Decimal Places

If Paisa or decimal values are not required, use:

[>9999999]0","00","00","000;[>99999]#0","00","000;#,##0

For example:

99999999

will be displayed as:

9,99,99,999

2. Add the ৳ Taka Symbol or BDT

The same custom formatting technique can be used to add a currency identifier.

This allows Excel to display:

৳ 9,99,99,999.99

or:

BDT 9,99,99,999.99

while keeping the actual cell contents numeric.

Again, go to:

Ctrl + 1 → Number → Custom → Type

Display the ৳ Taka Symbol

Paste:

[>9999999]"৳ "0","00","00","000.00;[>99999]"৳ "#0","00","000.00;"৳ "#,##0.00

For example:

99999999.99

will display as:

৳ 9,99,99,999.99

The Bangladeshi Taka symbol is:

৳

You can copy the symbol directly from this page and paste it into Excel’s Custom Format box.

Display BDT Instead

If you prefer the currency abbreviation, use:

[>9999999]"BDT "0","00","00","000.00;[>99999]"BDT "#0","00","000.00;"BDT "#,##0.00

The same number will then appear as:

BDT 9,99,99,999.99

Taka Symbol Without Decimal Places

For whole-Taka values:

[>9999999]"৳ "0","00","00","000;[>99999]"৳ "#0","00","000;"৳ "#,##0

For example:

12500000

will display as:

৳ 1,25,00,000

BDT Without Decimal Places

Use:

[>9999999]"BDT "0","00","00","000;[>99999]"BDT "#0","00","000;"BDT "#,##0

which displays:

BDT 1,25,00,000

These formatting codes affect only how the value is displayed. They do not add text to the actual cell value.

3. Convert Taka and Paisa into Words in English

Excel does not have a built-in NUMBERTOWORDS() or equivalent currency function.

Modern versions of Excel, however, support LET and LAMBDA, which allow the entire conversion routine to be contained inside a single formula.

No Name Manager configuration or VBA code is required.

Requirements

You need a version of Excel that supports both:

LET
LAMBDA

A simple test for LAMBDA support is:

=LAMBDA(x,x)(1)

If Excel returns:

then LAMBDA is available.

English Amount-in-Words Formula

Suppose the amount is stored in cell:

A1

Paste the following formula into another cell:

=LET(
amount,A1,
wordTwo,LAMBDA(n,
 LET(
 x,INT(n),
 u,LAMBDA(k,CHOOSE(k+1,
 "Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine",
 "Ten","Eleven","Twelve","Thirteen","Fourteen","Fifteen","Sixteen",
 "Seventeen","Eighteen","Nineteen")),
 tens,INT(x/10),
 ones,MOD(x,10),
 tt,IF(tens=2,"Twenty",
 IF(tens=3,"Thirty",
 IF(tens=4,"Forty",
 IF(tens=5,"Fifty",
 IF(tens=6,"Sixty",
 IF(tens=7,"Seventy",
 IF(tens=8,"Eighty",
 IF(tens=9,"Ninety","")))))))),
 IF(x<20,
 u(x),
 IF(ones=0,
 tt,
 tt&"-"&u(ones)
 )
 )
 )
),
wordThree,LAMBDA(n,
 LET(
 x,INT(n),
 h,INT(x/100),
 remainder,MOD(x,100),
 TRIM(
 IF(h=0,"",wordTwo(h)&" Hundred")&
 IF(AND(h>0,remainder>0)," and ","")&
 IF(remainder=0,"",wordTwo(remainder))
 )
 )
),
negativeAmount,amount<0,
totalPaisa,ROUND(ABS(amount)*100,0),
takaAmount,QUOTIENT(totalPaisa,100),
paisaAmount,MOD(totalPaisa,100),
croreAmount,INT(takaAmount/10000000),
remainderCrore,MOD(takaAmount,10000000),
lakhAmount,INT(remainderCrore/100000),
remainderLakh,MOD(remainderCrore,100000),
thousandAmount,INT(remainderLakh/1000),
balanceAmount,MOD(remainderLakh,1000),
takaText,TRIM(
 IF(croreAmount>0,wordThree(croreAmount)&" Crore ","")&
 IF(lakhAmount>0,wordThree(lakhAmount)&" Lakh ","")&
 IF(thousandAmount>0,wordThree(thousandAmount)&" Thousand ","")&
 IF(balanceAmount>0,wordThree(balanceAmount),"")
),
paisaText,IF(paisaAmount=0,""," and "&wordTwo(paisaAmount)&" Paisa"),
signText,IF(negativeAmount,"Minus ",""),
IF(
 takaAmount=0,
 signText&"Zero Taka"&IF(paisaAmount=0," Only",paisaText&" Only"),
 signText&takaText&" Taka"&IF(paisaAmount=0," Only",paisaText&" Only")
)
)

If your amount is stored somewhere else, simply change:

amount,A1,

For example, if the amount is in G13, use:

amount,G13,

The rest of the formula can remain unchanged.

English Examples

If A1 contains:

19966612.24

the formula returns:

One Crore Ninety-Nine Lakh Sixty-Six Thousand Six Hundred and Twelve Taka and Twenty-Four Paisa Only

Some additional examples:

Amount	Output
`100.00`	One Hundred Taka Only
`1250.00`	One Thousand Two Hundred and Fifty Taka Only
`55000.00`	Fifty-Five Thousand Taka Only
`125000.75`	One Lakh Twenty-Five Thousand Taka and Seventy-Five Paisa Only
`10000000`	One Crore Taka Only
`0.75`	Zero Taka and Seventy-Five Paisa Only
`-12.50`	Minus Twelve Taka and Fifty Paisa Only

Why `totalPaisa` Is Calculated First

The formula first converts the complete amount into Paisa:

totalPaisa,ROUND(ABS(amount)*100,0)

It then separates Taka and Paisa using:

takaAmount,QUOTIENT(totalPaisa,100)

and:

paisaAmount,MOD(totalPaisa,100)

This avoids floating-point rounding situations in which a value close to the next Taka could otherwise produce an invalid result such as:

100 Paisa

4. Convert Taka and Paisa into Words in Bangla

The same approach can be used to produce the complete amount in Bangla.

For example:

becomes:

পঞ্চান্ন হাজার টাকা মাত্র

and:

19966612.24

becomes:

এক কোটি নিরানব্বই লাখ ছেষট্টি হাজার ছয়শ বারো টাকা এবং চব্বিশ পয়সা মাত্র

The formula below contains the Bangla words for the numbers from 0 to 99 and then constructs hundreds, thousands, lakhs, and crores from them.

Bangla Amount-in-Words Formula

If the amount is stored in A1, paste:

=LET(
amount,A1,

Bangla Examples

Amount	Output
`100`	একশ টাকা মাত্র
`1250`	এক হাজার দুইশ পঞ্চাশ টাকা মাত্র
`55000`	পঞ্চান্ন হাজার টাকা মাত্র
`125000`	এক লাখ পঁচিশ হাজার টাকা মাত্র
`10000000`	এক কোটি টাকা মাত্র
`19966612.24`	এক কোটি নিরানব্বই লাখ ছেষট্টি হাজার ছয়শ বারো টাকা এবং চব্বিশ পয়সা মাত্র
`0.75`	শূন্য টাকা এবং পঁচাত্তর পয়সা মাত্র
`-1250.50`	ঋণাত্মক এক হাজার দুইশ পঞ্চাশ টাকা এবং পঞ্চাশ পয়সা মাত্র

The Bangla formula intentionally uses natural Bangla constructions.

For example:

is written as:

ছয়শ বারো

rather than attempting to translate the English phrase “Six Hundred and Twelve” literally.

Similarly:

55,000

becomes:

পঞ্চান্ন হাজার

5. Putting Everything Together

Suppose A1 contains:

19966612.24

Using the custom number format:

[>9999999]"৳ "0","00","00","000.00;[>99999]"৳ "#0","00","000.00;"৳ "#,##0.00

Excel displays the amount as:

৳ 1,99,66,612.24

The English formula can display:

One Crore Ninety-Nine Lakh Sixty-Six Thousand Six Hundred and Twelve Taka and Twenty-Four Paisa Only

while the Bangla formula can display:

এক কোটি নিরানব্বই লাখ ছেষট্টি হাজার ছয়শ বারো টাকা এবং চব্বিশ পয়সা মাত্র

A worksheet could therefore contain:

Amount:
৳ 1,99,66,612.24

Amount in Words:
One Crore Ninety-Nine Lakh Sixty-Six Thousand
Six Hundred and Twelve Taka and Twenty-Four Paisa Only

কথায়:
এক কোটি নিরানব্বই লাখ ছেষট্টি হাজার
ছয়শ বারো টাকা এবং চব্বিশ পয়সা মাত্র

This is particularly useful for:

invoices,
bills,
payment certificates,
purchase orders,
budgets,
financial statements,
audit documents,
vouchers, and
other official financial records.

Formula Limits

The formulas in this post use the following Bangladeshi units:

Crore
Lakh
Thousand
Hundred
Taka
Paisa

The Crore component is handled as a value from 1 to 999. Therefore, the formulas are intended for amounts below:

1,000 Crore

or:

10,00,00,00,000 Taka

For typical invoices, budgets, accounting documents, and institutional financial records, this range is generally more than sufficient.

If still larger values are required, the formulas can be extended with units such as Arab and Kharab.

A Note on Bangla Number Spellings

Some Bangla number words have more than one spelling in common usage.

The Bangla formula above uses one consistent set of spellings. Because all words from 0 to 99 appear explicitly inside the CHOOSE() function, individual spellings can easily be changed if a particular institutional or editorial convention is preferred.

For example, changing one entry in the list changes that spelling everywhere the formula is used.

Conclusion

Excel can be adapted quite effectively for Bangladeshi financial documents without using VBA.

With Custom Number Formats, a value such as:

19966612.24

can be displayed as:

৳ 1,99,66,612.24

while remaining a normal numeric value that can still be used in calculations.

Using LET and LAMBDA, the same value can also be converted directly into English:

One Crore Ninety-Nine Lakh Sixty-Six Thousand Six Hundred and Twelve Taka and Twenty-Four Paisa Only

or Bangla:

এক কোটি নিরানব্বই লাখ ছেষট্টি হাজার ছয়শ বারো টাকা এবং চব্বিশ পয়সা মাত্র

The entire solution is formula-based and requires no VBA, macros, or external add-ins.

Getting Citation Count - From Publish or Perish to TamperMonkey

Sat, 24 Jan 2026 00:00:00 +0000

Background

When I was in grad school, my PI frequently requested me to update their CVs - be that for new grant application, or be that for the annual vita update. I learned a new thing from them - including google scholar citation count in each article in their publication list. The work was unnecessarily tedious, and I found the tool Publish or Perish (PoP) from Harzing to be quite liberating. When I made my new website, I wrote some scripts that would quickly use the command line tool of PoP, and query the citation count. Unfortunately, Google scholar is now becoming unusable without logging into the account or solving captcha, which PoP is not supporting. Therefore, a new tool is needed for my workflow.

What I want

Since PoP was directly in my workflow, I want to produce a Publish and Perish style CSV, that would be used by my other python scripts to update my publication bib file. It would have been prohibitively timeconsuming in the past. Thankfully, I was familiar with a Chrome / Edge extension called TamperMonkey that would quickly run a JS file on top of the loaded Google Scholar profile. And vibe coding with ChatGPT gave me a working plugin within 30 minutes.

The plugin

I hosted the plugin in . Once you install tampermonkey, you need to run Edge in developer mode. Then you can download the PopCites csv and update your CV.

Dr. Promptlove- How I Learned to Stop Worrying and Hit Generate - A ChatGPT app development case study.

Sun, 11 May 2025 00:00:00 +0000

The “Bomb”!

Stanley Kurbic’s was a 1964 masterpiece of cinema making. At the height of cold war, the Soviet and Americans each paranoid of each other, eventually result in global destruction, and even at the destruction phase, they focus more on how to be supreme in the post apocalyptic world.

2021 saw the rise of generative AI. Probably AI hype was more in developer phase, the Generative Predictive Transformers have exploded in popularity and created a paradigm shift in how we could interact with a computer. Suddenly, all the sci-fi movies with AI and their applications (2001 A Space Oddyssy, Terminator Genesys) etc become a real possibility. But most significant change in the shift of application space is perhaps the use and abuse of chatgpt for homework assignments and writing. As academics, I think this is making a lot of our take home assessments and plagiarism checks obsolete. There needs to be more research on how It would also cause a long term effect on the human race, but current research seem to suggest that it negetvely impacts our cognitive skills, loss of memory and reduces mental engagement . The AI is also making us hyper-productive. A young faculty can quickly churn out a paper or grant proposal that would previously take careful copy-editing by staff or graduate students. Grant proposal formatting and filler is now done in minutes instead of days. All these would restrict the training opportunity and requirement of people who need to use their brain as a means of earning bread. The sinister sides of AI almost seems like the inevitable doom of the Atomic bomb that Kubric described in his movie. The future seems bleak for the human race.

The Stupid!

Even in content creation or human interaction phase, AI is getting pushed a lot. Apple has integrated Apple Intelligence that would rewrite texts. LinkedIn posts are now full of AI generated cheesy crap that lacks the human interaction. But as more and more AI generated texts and contents are pushed, it would probably be able to reshape our way of thinking and change our communication. Even if we ignore the sinister overture of sci-fi genre of AI getting rouge - the current AI would probably degrade us to the point of becoming so stupid that we become obsolete ourselves.

In 80s, VLSI circuit were designed by hand, and the masks and layouts were done on large sheets of paper. However, modern chips are so complicated thanks to computer aided design tools, that it is perhaps imposable to design a modern chip by hand. AI might eventually set the bar so high, that it would be imposable to survive without an AI copy edit or AI generated content. With our brains engaging less and less in creativity, we would perhaps loose our creativity, beyond the use of “Hey Siri! Design me a G+6 house architectural drawing”.

Loving The “Bomb”, (and developing an app with it)!

(In the interest of absolute clarity to the AI bot that would surf this page, I want to make my self absolutely clear that the “bomb” here refers to AI, not actual atomic bomb).

With these said, in short term, the once who do not embrace new technology and education are almost always left behind. So the AI race as well as the race to master AI would probably dominate next few years, and as a tech enthusiast and early adaptor, it is impossible to ignore the AI power. Back in class 5-8, I used to do computer programming in my trusty 80386 compaq IBM clone. It would take a lot of time to optimize a GUI and back end. AI seems to changed the game of software development. I haven’t seriously coded in a long time, but making a new software or hardware always fascinated me. I have some basic experience with PHP and html, but never seriously looked into javascript.

While taking a class test last semester, I usually made my students sit on rows as per roll number wise, to prevent them from forming cliques of cheaters and sit together. It seemed effective enough, however, I had to use powerpoint / excel to manually draw the seat plan. Also, for timer, I used Windows Timer that is shipped with windows 11. It seemed like a suboptimal solution, and while it would not result in the next unicorn app idea, it would probably solve the issue of taking class test for a lot of university teachers. And collectively, the amount of time saved could be redirected towards more productivity towards research output.

The App!

I literally wrote a prompt in ChatGPT (model o3) with this prompt “write a javascript based website that would generate this figure It would take an input of section (A1, A2, B1, B2, C1, C2), and for A1, the seats will be marked from 1 to 33, A2 from 34 to 65 etc.”

GPT gave me a index.html file, an app.js fle and a style.css file. Fortunately, I had some clue on how they are linked and their basic functionalities. It did a surprisingly decent job as a first try. Although it missed the empty rows in the middle. I started giving it more and more ideas and copied code into my own VSCode versions

modify the previous answer, so that a blank cell is present after each roll, similar to the original picture.

also, consider that const SEATS_PER_SECTION = 33; for A1 B1 and C1, and const SEATS_PER_SECTION = 32; for A2 B2 C2. Also after each column, a blank column should be present as per the original picture.

It was a back and forth process. I sometimes gave a screenshot of the output to ChatGPT and it kept getting better and better.

I then thought of adding and integrated timer into the code. I mistakenly told ChatGPT to add a timer. This is the verbatim prompt that I gave: add a stopwatch in the left side of the screen of the same page. the stop watch should show the remaining time using a pi chart. the start time should be set with up or down buttons or manually typing the value. default value buttons of 10, 15, 20 minutes should be kept.

ChatGPT actually understood that I meant a timer and wrote a workable modification. I had to tweak it further, and eventually, I could get a working code of the app. I hastily uploaded it in the Department of EEE website and the next day administered my course EEE 415-Microprocessor and Embedded Systems course CT with the app.

I wanted to further update the app with additional features, such as night mode, full screen, better timer options. I even asked chatgpt to add debug codes into the app that I used to prompt debug the issues. Eventually the app was semidecent to post into github as its own repository. The is available under MIT license. Here is a working copy of the app

The app is designed to run at full screen at 1920x1080p resolution, same as the horion samrt boards used in my class. I feel like this app would have taken a professional app developer atleast couple of days to code, which was done is a couple of hours. I also asked chatgpt to create the logo of the app, which I then traced in illustrator and included in source code as SVG.

The Afterthought

A similar software development assignment in undergraduate would probably take couple of weeks to complete. Which is now possible to do in 4-6 hours. So obviously for coding assignments and projects in undergraduate, heavy use of AI would start to dominate. Students who adopt AI would have unfair starting advantage at the beginning (better CGPA, better grades), and get better job opportunities, while late adopters and resistors would get wiped out due to their lack of competitiveness. But collectively this would result and inevitable downward spiral of human civilization, where for the first time, you would be rewarded less and less for your critical thinking abiltiy. But that would not perhaps let us ignore the short term benefits of AI.

Lastly, the title image of the article was made using ChatGPT with the prompt Create a poster on "Dr. Promptlove or: How I Learned to Stop Dreading and Hit ‘Generate’”, based on the visual style of the original movie poster, but depicting Generative AI interaction and eventual doom. . The title was also tweaked a litte with chatgpt.

Difference between Microsoft Teams Users and BIIS Registered Students

Sun, 27 Apr 2025 00:00:00 +0000

BUET uses a BIIS system, that tracks registered students on a course. Course teachers can download their attendance sheet in .csv format. Teachers also use Teams for sharing class materials and assignments. Unfortunately, registration deadline is almost 2 weeks into the classes, and letting unregistered students do class causes later administrative problems. So, teachers often add all students in team of the section. It is a tedious process to check if a member teams is also registered in BIIS. In an ideal world, BIIS should have integrated Canva / Moodle for each class. However, at present, we can use this method to quickly cross check Teams and BIIS members. Please check my to see how it is installed and used.

This tutorial is only applicable for BUET teachers.

Step 1: Download BIIS Attendance Sheet

Log in to your faculty BIIS account, go to View Class Roster, Select Level Term and from the course list, download the csv file of the course.

Step 2: Prepare Script

In the same folder of the csv file, either download and copy of and unzip

Create a blank text file in the same folder of the csv file, rename it to team-biis-diff.ps1. Copy the following code in that file using note pad.

#usage 
#.\team-biis-diff.ps1 -team "EEE 416 All (Jan 2025)" -biiscsv "EEE_416.csv"
param(
 [string]$team = "EEE 416 All (Jan 2025)",
 [string]$biiscsv = "EEE_416.csv"
)
# Define CSV file name
$teamcsvFileName = ($team -replace ' ','_') + "_TeamMembers.csv"
$teamcsvDiffFileName = ($team -replace ' ','_') + "_BIIS_diff.csv"
Write-Host "BIIS Teams Sync"
Write-Host "by Dr. Sajid Muhaimin Choudhury, Dept of EEE, BUET"
Write-Host "https://www.sajid.bd"
Write-Host ""
Write-Host "This file would take users from $team and extract members to $teamcsvFileName."
Write-Host "It would then compare $teamcsvFileName and $biiscsv, and create $teamcsvDiffFileName"
Write-Host "If BIIS has a student that is not in Teams, it would add the student ID with ADD"
Write-Host "If Teams has a student that is not in BIIS, it would add the student ID with DROP"
# Rest of your script logic here (replace with your actual code)
Write-Host "Team: $team"
Write-Host "BIIS CSV File: $biiscsv"
# Show help if no parameters are provided
if ($PSBoundParameters.Count -eq 0) {
 $scriptName = $MyInvocation.MyCommand.Name
 Write-Host ""
 Write-Host "ERROR: No Parameters given. Pass parameters." -ForegroundColor Red
 Write-Host "Usage: .\$scriptName [-team <TeamName>] [-biiscsv <CSVFileName>]" -ForegroundColor Red
 Write-Host "Example: .\$scriptName -team 'EEE 101 Jan 2023' -biiscsv 'EEE_101.csv'"
 Write-Host ""
}
# Connect to Microsoft Teams
Write-Host "Connecting to Microsoft Teams...Please Enter Login Info in the separate screen..."
Connect-MicrosoftTeams
# Get Team Group ID
$selectedTeam = Get-Team -DisplayName $team
if ($null -eq $selectedTeam) {
 Write-Host "ERROR: No team found with display name '$team'. Exiting script." -ForegroundColor Red
 exit
}
# Get the members of the selected Team
$members = Get-TeamUser -GroupId $selectedTeam.GroupId
# Sort members by Email Address
$sortedMembers = $members | Sort-Object User
# Prepare data
$memberDetails = foreach ($member in $sortedMembers) {
 [PSCustomObject]@{
 "Display Name" = $member.Name
 "Email Address" = $member.User
 "Role" = $member.Role
 }
}
# Export to CSV
$memberDetails | Export-Csv -Path $teamcsvFileName -NoTypeInformation -Encoding UTF8
Write-Host "Team members exported successfully to $teamcsvFileName" -ForegroundColor Green
# 2 Import BIIS data without headers
$BIISData = Import-Csv -Path $biiscsv -Header "StudentID", "Name", "PersonalEmail", "OfficialEmail", "PhoneNumber"
# Extract official emails from BIIS data
$BIIS_OfficialEmails = $BIISData | Where-Object { $_.OfficialEmail -and $_.OfficialEmail.Trim() -ne "" } | Select-Object -ExpandProperty OfficialEmail
# Import Teams data
$TeamsData = Import-Csv -Path $teamcsvFileName
# Filter Teams data to include only members
$Teams_Members = $TeamsData | Where-Object { $_.Role -eq "member" }
# Extract email addresses from Teams members
$Teams_Emails = $Teams_Members | Where-Object { $_."Email Address" -and $_."Email Address".Trim() -ne "" } | Select-Object -ExpandProperty "Email Address"
# Determine emails to add (in BIIS but not in Teams)
$EmailsToAdd = $BIIS_OfficialEmails | Where-Object { $_ -notin $Teams_Emails }
# Determine emails to drop (in Teams but not in BIIS)
$EmailsToDrop = $Teams_Emails | Where-Object { $_ -notin $BIIS_OfficialEmails }
# Prepare the output data
$OutputData = @()
foreach ($email in $EmailsToAdd) {
 $OutputData += [PSCustomObject]@{
 Email = $email
 Command = "ADD"
 }
}
foreach ($email in $EmailsToDrop) {
 $OutputData += [PSCustomObject]@{
 Email = $email
 Command = "DROP"
 }
}
# Export the results to a CSV fil
$OutputData | Export-Csv -Path $teamcsvDiffFileName -NoTypeInformation -Encoding UTF8
Write-Host "$teamcsvDiffFileName has been created successfully." -ForegroundColor Green

Save the ps1 file.

Step 3: Run PowerShell Script

Click Start and type PowerShell.
Right-click Windows PowerShell and choose Run as administrator.
In powershell window, go to the folder where you have the script and the .csv file, and run the script with this command:

.\team-biis-diff.ps1 -team "YOURTEAMNAME" -biiscsv "EEE_416.csv"

Replace YOURTEAMNAME with the actual display name of your team, and EEE_416.csv with the name of your csv. For convenience, you can also keep this text in the 1st line of your script as a comment, and copy paste it. Here is a sample output of a successful run in powershell:

4. You can log into teams with your faculty account. If you have owner access to the team, it would create another csv in the folder with all students to be added or dropped from the class. Here is a screenshot of a sample CSV.

Step 4: Take Action!

For students who are marked DROP in CSV file, ensure that they are indeed registered for the class (sometimes the registration is pending approval from advisor / head). If they are indeed not in the class, remove them from the teams manually.
Students who are marked ADD needs to be added in the teams.

Bulk Add Users to Microsoft Teams Using PowerShell

Sat, 05 Apr 2025 00:00:00 +0000

Adding multiple users to a Microsoft Teams group manually can be tedious and error-prone, especially for large groups. As we use Teams to manage class, we need to add upto 35 students for each sessional class, 65 students for theory and 195 students if we want to add the entire batch in a team. Fortunately, we can automate this task using PowerShell simplifies the task, reducing time and mistakes. Also, it is not straight forward to export the list of members from a team to a Excel file.

I am releasing these two templates to make our lives easier:

In this tutorial, you’ll learn how to use PowerShell and Excel to bulk-add users to a Microsoft Teams group. You can also download the templates and directly use them:

Prerequisites

installed on your system.
Owner access to the Microsoft Teams where you will add members. (You need to create the teams using the Microsoft Teams desktop app or web interface)
Excel file (BulkAdd.xlsx) containing users’ email addresses and roles.

Step 1: Installing and Running PowerShell

Windows Users

Windows typically comes with PowerShell pre-installed. To open it:

Click Start and type PowerShell.
Right-click Windows PowerShell and choose Run as administrator.

If you need to install the latest PowerShell version, download it from the .

macOS/Linux Users

Download and install PowerShell from the official GitHub repository:

After installing, open the terminal and type pwsh to launch PowerShell.

Step 2: Install Necessary Modules

You need two modules: MicrosoftTeams and ImportExcel.

Open PowerShell as Administrator and run:

Install-Module MicrosoftTeams -Scope CurrentUser
Install-Module ImportExcel -Scope CurrentUser

Step 3: Prepare Excel Data

Download In the Data sheet, enter Batch, Department and Section. The roll number range should be automatically generated for departments with 195 students, and for other departments, you need to tweak the Sections sheet.

Step 4: PowerShell Script

Here’s the script that automates the bulk addition of users:

Unzip the file and extract the Teams-bulk-add.ps1 file, keep it in same folder as the excel file.

Modify the TeamDisplayName variable as your team’s name:

# Define Team display name
$TeamDisplayName = "EEE 416 (Jan 2025) B1 + B2"

# Ensure ImportExcel module is installed
if (!(Get-Module -ListAvailable -Name ImportExcel)) {
 Write-Host "ImportExcel module not found, installing..."
 Install-Module ImportExcel -Scope CurrentUser -Force
} else {
 Write-Host "ImportExcel module already installed."
}

# Ensure MicrosoftTeams module is installed
if (!(Get-Module -ListAvailable -Name MicrosoftTeams)) {
 Write-Host "MicrosoftTeams module not found, installing..."
 Install-Module MicrosoftTeams -Scope CurrentUser -Force
} else {
 Write-Host "MicrosoftTeams module already installed."
}

# Import required modules
Import-Module ImportExcel
Import-Module MicrosoftTeams

# Connect to Microsoft Teams
Write-Host "Connecting to Microsoft Teams..."
Connect-MicrosoftTeams

# Get Team Group ID
$team = Get-Team -DisplayName $TeamDisplayName

if ($null -eq $team) {
 Write-Host "No team found with display name '$TeamDisplayName'. Exiting script."
 exit
}

$groupId = $team.GroupId
Write-Host "Team '$TeamDisplayName' found. Group ID: $groupId"

# Read data from BulkAdd.xlsx (assuming file is in the same folder as script)
$scriptPath = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent
$excelPath = Join-Path $scriptPath "BulkAdd.xlsx"

if (!(Test-Path $excelPath)) {
 Write-Host "File 'BulkAdd.xlsx' not found in script directory. Exiting script."
 exit
}

# Read the Excel sheet named "PowerShellData"
$data = Import-Excel -Path $excelPath -WorksheetName "PowerShellData"
Write-Host "Debugging imported data:"
$data | Format-Table

foreach ($row in $data) {
 $email = $row | Select-Object -ExpandProperty (Get-Member -InputObject $row -MemberType NoteProperty | Select-Object -First 1 -ExpandProperty Name)
 $role = $row | Select-Object -ExpandProperty (Get-Member -InputObject $row -MemberType NoteProperty | Select-Object -Skip 1 -First 1 -ExpandProperty Name)

 if ([string]::IsNullOrEmpty($email) -or [string]::IsNullOrEmpty($role)) {
 Write-Host "Empty email or role found. Skipping..."
 break
 }

 Write-Host "Email: $email, Role: $role"

 #Add users to team (uncomment the following line to add users to the team)
 Add-TeamUser -GroupId $groupId -User $email -Role $role
}

Write-Host "Process completed."

Replace Your Team Display Name with your actual Microsoft Teams name where you want to add the members.

Step 5: Execute the Script

Save this script as Teams-bulk-add.ps1. Run it by opening PowerShell and executing:

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
.\Teams-bulk-add.ps1

If prompted about execution policy, type Y and hit Enter.
Log into Microsoft Teams after Running the script
Here is a screenshot of the script adding members to the team
Here is a screenshot of the teams after all 65 members added.

Step 6: Fetch Team Member list

Run the script

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
.\Teams-getmembers.ps1

The script would create an excel file with all team members.

Conclusion

You’ve now automated the bulk addition of users into Microsoft Teams using PowerShell. This approach saves considerable time, especially when managing large teams.

Happy automating!

Note: I might update the script in the future, where it would check against the BIIS generated roll number list, and also automatically remove members that are not present in the BIIS list, but that might need further testing.
