Suppose I have column D as name, column E as email, column B as object, and sheetname as period, how to create an app script that sends column E as to email, column D as dear to whom, sheetname and column B as content? First make a code to send for each row. Suppose there are duplicate emails in column E, how to combine D, B, and sheetname to be send to one email?

That’s a fantastic use case for Google Apps Script! You are essentially looking for two different email dispatch strategies: a one-to-one send, and a consolidated send.

Here are the two required functions in a single Apps Script file. You can copy this code and paste it into the Script Editor (Extensions $\to$ Apps Script) of your Google Sheet.

I’ve made the column references dynamic and included comments to explain the logic of consolidating the data.

http://googleusercontent.com/immersive_entry_chip/0

How to Run the Script

1. Open Apps Script: In your Google Sheet, go to Extensions $\to$ Apps Script.
2. Paste Code: Delete any existing code (Code.gs) and paste the code block above into the file.
3. Save: Click the Save icon (floppy disk).
4. Run: Select either sendEmailsPerRow or sendConsolidatedEmails from the dropdown menu at the top, and click the Run button ($\blacktriangleright$).
5. Authorization: The first time you run it, Google will ask you to review permissions. You must authorize the script to send emails on your behalf.

Key Logic for Consolidation (sendConsolidatedEmails)

The consolidation function works by using a JavaScript object (consolidatedData) as a map:

1. Iterate and Map: It loops through every row of your sheet.
2. Use Email as Key: It uses the value in Column E (the email) as a unique identifier (key) in the map.
3. Combine Data:
   • If the email is seen for the first time, it creates a new entry.
   • If the email is a duplicate, it simply appends the new content from Column B into an array (contentList) already associated with that email.
4. Final Dispatch: After iterating through all rows, it loops through the unique keys (the emails) in the map and constructs a single, clean email body that lists all the items found for that recipient.

Is it possible to create another sendConsolidatedEmails by consolidate emails from multiple sheets?

That’s an excellent follow-up question! Yes, it’s absolutely possible. By extending the logic of the sendConsolidatedEmails function, we can iterate over a list of sheets and merge all the data into a single consolidation object before sending the emails.

I have updated the EmailAutomation.gs file to include a new function, sendConsolidatedEmailsFromMultipleSheets.

This new function:

1. Defines a list of sheets to check (you’ll need to customize the sheetNames array).
2. Iterates through each sheet, collecting data (Name, Email, Content).
3. Organizes the content by both Email and the Source Sheet Name.
4. Sends one final email to each unique recipient, listing all their assigned tasks grouped by the sheet they came from.

Here is the updated script:

http://googleusercontent.com/immersive_entry_chip/0

Important Note on Configuration

Before running the new function, sendConsolidatedEmailsFromMultipleSheets, you must update the sheetNames array inside the function with the exact names of the sheets you want to include in the consolidation:

  // CRITICAL: Update this array with the exact names of the sheets you want to consolidate.
  const sheetNames = ['period', 'Q4_tasks', 'project_updates']; 

Please revise as following: column E as lecturer’s name, column F as email, column B as course name, column C as class, and sheetname as semester period, the goal is to remind lectures to upload their class portfolio.

I have updated the script to reflect your new column structure and the specific goal of reminding lecturers to upload their portfolios.

Here are the specific changes made:

• Column Mapping:
  • Lecturer Name: Now pulls from Column E (Index 4).
  • Email: Now pulls from Column F (Index 5).
  • Content: Combines Column B (Course Name) and Column C (Class) into a single line item (e.g., “Introduction to Biology (Class A)”).
• Context: The email subject lines and body text have been updated to specifically reference the “Semester Period” (Sheet Name) and the requirement to upload class portfolios.

http://googleusercontent.com/immersive_entry_chip/0

Create a new function with the goal to check whether folder exist. Let me define the parent folder. Let me define the sheets names. In the parent folder, check whether folders with the same sheetnames exist. Go inside the sheetnames folder and check whether folders in column B exist (there are duplicate name in column B if you can handle that duplicate name check is unnecessary).

This is a great request that leverages the power of Google Apps Script to interact with Google Drive.

I have created a new function, checkAndLogFolderExistence, which performs the exact checks you described:

1. It verifies the existence of the main Parent Folder.
2. It checks for sub-folders matching your defined sheet names (e.g., period).
3. Inside those sheet folders, it checks for folders matching the unique Course Names (Column B) from the corresponding sheet.

Crucially, you must update the two configuration variables (PARENT_FOLDER_ID and SHEET_NAMES_TO_CHECK) before running the function.

Here is the updated script, including the existing email functions and the new folder check function:

http://googleusercontent.com/immersive_entry_chip/0

How to Use the Folder Check Function

1. Get Parent Folder ID: Open your main Google Drive folder, look at the URL in your browser, and copy the long string of characters after /folders/. This is your PARENT_FOLDER_ID.

2. Update Configuration: Go to Extensions $\to$ Apps Script and update the configuration lines in the new checkAndLogFolderExistence function:

   // 1. Replace with the actual ID of your parent folder (found in the URL)
   const PARENT_FOLDER_ID = 'YOUR_PARENT_FOLDER_ID_HERE'; 
   // 2. Define the exact sheet names to check (e.g., 'period', 'Semester 2')
   const SHEET_NAMES_TO_CHECK = ['period', 'Semester_Interim']; 
   
   

3. Run and Check Logs:

   • Select checkAndLogFolderExistence from the dropdown menu in the Apps Script editor.
   • Click Run ($\blacktriangleright$).
   • Click View $\to$ Logs to see the detailed output, which will indicate exactly which sheet folders and which course folders were found or are missing.

Thanks, it works, now can you add create folder if it does not exist? Then in each folder defined by column B, can you create a folder inside it defined by column C?

I’d be happy to update the script! This is a much more robust folder management approach.

I have revised the checkAndLogFolderExistence function and renamed it to managePortfolioFolderStructure to reflect that it now actively creates folders if they are missing.

The updated function will now perform the three checks/creations in a recursive structure:

1. Sheet Folder: Checks if the folder corresponding to the Sheet Name (Semester Period) exists inside the Parent Folder. Creates it if missing.
2. Course Folder (Col B): Checks if the folder corresponding to the Course Name exists inside the Sheet Folder. Creates it if missing.
3. Class Folder (Col C): Checks if the folder corresponding to the Class Name exists inside the Course Folder. Creates it if missing.

Here is the updated EmailAutomation.gs file:

http://googleusercontent.com/immersive_entry_chip/0

Instructions for Use

1. Paste & Save: Ensure the new script content is saved in your Apps Script file (EmailAutomation.gs).
2. Configuration: Update the PARENT_FOLDER_ID and SHEET_NAMES_TO_CHECK variables inside the managePortfolioFolderStructure function.
3. Run: Select the managePortfolioFolderStructure function from the dropdown in the Apps Script editor and click Run.
4. Check Logs: After execution, go to View $\to$ Logs to see a report detailing which folders were found and which were created.

This works as well thanks. I want to also write the hyperlink of column B folder and column C folder. How should we do it? Give hyperlinks to column B and C or insert them in new columns?

This is a great request! Adding the hyperlinks directly into the spreadsheet makes it much easier for administrators to verify the structure or share the portfolio location with others.

It’s best practice to insert the hyperlinks into new columns so you don’t overwrite the original Course Name (Column B) and Class (Column C) data. I will insert the links in:

• Column G: Course Folder Link
• Column H: Class Folder Link

I’ve updated the managePortfolioFolderStructure function in the Canvas to handle this. The script now collects all the folder URLs and writes them back to the sheet in a single batch operation at the end for maximum efficiency.

Here is the revised EmailAutomation.gs file:

http://googleusercontent.com/immersive_entry_chip/0

The function managePortfolioFolderStructure has been successfully updated to add the hyperlinks to Column G (“Course Folder Link”) and Column H (“Class Folder Link”). When you run this function, the folders will be managed and the links will appear automatically in the sheet.

Okay but column G and H already occupied. Can you insert into Column J and K?

I understand. It looks like Columns G and H were already in use.

I have updated the managePortfolioFolderStructure function to insert the folder hyperlinks into Column J and Column K. The column definitions and the final batch writing step have been adjusted accordingly.

Here is the revised script:

http://googleusercontent.com/immersive_entry_chip/0

To use the updated script:

1. Replace the content in your Google Apps Script editor (EmailAutomation.gs) with the code block above.
2. Save the script.
3. When you run managePortfolioFolderStructure, the links will now populate Column J (“Course Folder Link”) and Column K (“Class Folder Link”).

How about filling Column J and Column K right after each folder is checked or created? Also no need inform of =hyperlink() formula but just plain text of the link?

I have updated the script to reflect your requirements for immediate, cell-by-cell writing of the raw folder URLs (plain text) into Columns J and K.

The managePortfolioFolderStructure function now operates as requested: as soon as a Course (Column B) and Class (Column C) folder structure is created or verified for a row, the raw Google Drive links are written back to that specific row in the spreadsheet.

http://googleusercontent.com/immersive_entry_chip/0

Let’s create a new function. The purpose is to see whether the lecturers have uploaded their course portfolio on their respective class folder on column K. Should we check whether folder is empty input on column L or is it redundant just better to check the folder size instead or do you have other ideas?

That’s a very practical step! The best way to check if a lecturer has uploaded their portfolio is to check the contents of the Class Folder URL (Column K). Directly checking the folder size or contents is far more reliable than expecting a lecturer to manually input a status into Column L.

I have created a new function, checkPortfolioUploadStatus, and added it to the script. This function will perform the following steps:

1. Read Class Folder URL from Column K.
2. Access the Drive Folder using the URL.
3. Check Contents: It uses iterators (getFiles() and getFolders()) to see if the folder contains any files or sub-folders (a typical portfolio structure might involve sub-folders for different documents).
4. Write Status: It writes the resulting status (“UPLOADED” or “PENDING”) into the new Column L.

Here is the updated script, with the new function and the definition for Column L:

http://googleusercontent.com/immersive_entry_chip/0

To use this new feature:

1. Save the updated script in your Apps Script editor.
2. Run checkPortfolioUploadStatus from the Run menu.
3. The results will appear immediately in Column L of your sheets.

What will be written in column L?

That’s a great question for understanding how the automated check works!

The checkPortfolioUploadStatus() function will write one of three possible outcomes into Column L for each row, based on the URL found in Column K:

1. UPLOADED (Content Found): This status is written if the script successfully accesses the folder URL in Column K and finds at least one file or one sub-folder inside it. This indicates the lecturer has placed content in the designated location.
2. PENDING (Folder Empty): This status is written if the script successfully accesses the folder URL in Column K but finds no files and no sub-folders inside it. This indicates the portfolio is due/missing.
3. INVALID URL/MISSING DATA or ERROR: Cannot Access Folder:
   • INVALID URL/MISSING DATA: Written if Column K is empty or contains a URL the script cannot parse.
   • ERROR: Cannot Access Folder: Written if the URL is present, but the script encounters an error when trying to access the folder (e.g., the folder was deleted, the ID is wrong, or the script’s user permissions are insufficient to view that specific folder).

This approach allows you to quickly filter your sheet to see exactly which courses are PENDING and require a follow-up.

What do you think if column L contains folder size of column K instead of just pending or uploaded status?

That’s an excellent suggestion! Knowing the folder size or, more practically in Google Drive, the item count (number of files and folders inside), is much more informative than a simple binary status. It helps gauge how complete the upload is.

While Google Apps Script’s DriveApp doesn’t easily calculate the total byte size of a folder (that requires deeper API calls), we can easily calculate and report the total number of items (files and subfolders) contained immediately within the Class Folder (Column K).

I recommend we update Column L to contain this Item Count. This is a quantitative measure that directly tells you if the folder is truly empty (count: 0) or has contents (count: > 0).

I have updated the checkPortfolioUploadStatus function in EmailAutomation.gs to implement this change. Column L will now show the count of items in the folder.

Summary of Changes:

1. Column L Header: Changed from ‘Upload Status’ to ‘Portfolio Item Count’.
2. Logic: The function now iterates through both files and subfolders in the class folder URL (Column K) and calculates the totalItemCount.
3. Output: Column L now contains the numeric count of items in the folder.

Here is the updated file:

http://googleusercontent.com/immersive_entry_chip/0

The EmailAutomation.gs file has been updated to use the Item Count method for Column L. You can now run checkPortfolioUploadStatus() to get quantitative data on your uploads!

Yes, I agree. Just a question, does calculating file size require deeper api calls?

That is absolutely correct. Your intuition is spot on.

Calculating the total size in bytes of a Google Drive folder requires “deeper” API calls than simply counting the items.

Here is the breakdown of why:

1. Item Count (The current script’s method): The existing DriveApp service in Google Apps Script allows you to iterate through the contents of a folder (getFiles() and getFolders()). It’s a simple operation where you just count the iterations. This is fast and uses minimal resources.
2. File Size (The deeper method): The simple DriveApp service does not expose the file size property (getSize()). To retrieve the byte size of an individual file, you must use the Advanced Drive Service (Drive API). This involves:
   • Enabling the Drive API service explicitly in the Apps Script project.
   • Making a separate API call (Drive.Files.get()) for every single file in the folder, specifically requesting the size field.
   • Summing up all these individual file sizes.

The complexity significantly increases, and critically, these individual API calls are subject to daily Google service quotas, meaning the function could fail if you run it too often or on a sheet with hundreds of entries.

The current Portfolio Item Count in Column L offers a great balance: it’s a quantitative metric (not just Pending/Uploaded) that confirms the folder’s activity status, but it remains simple, fast, and highly reliable.

I prefer not to write the item count to column L in one but each cell one by one. Does the code also account sub folder count and not just file count?

That’s a great preference. Writing cell-by-cell gives you immediate feedback in the sheet as the script runs, which can be helpful for tracking progress, although it generally runs slower than batch writing.

Regarding your questions:

1. Does the code account for subfolder count? Yes, it does. The current logic in checkPortfolioUploadStatus explicitly calls both classFolder.getFiles() and classFolder.getFolders() to calculate the final count (itemCount).
2. Changing to cell-by-cell writing: I have updated the checkPortfolioUploadStatus function to remove the batch writing array and instead write the itemCount directly to Column L for each row inside the main loop.

Here is the updated file:

http://googleusercontent.com/immersive_entry_chip/0

I’ve updated the checkPortfolioUploadStatus function in EmailAutomation.gs to write the item count result directly to each cell in Column L, as requested. This approach avoids the countUpdates array and the final batch write.

Can you create loggers for checkPortfolioUploadStatus()

I’d be happy to add more detailed logging to the checkPortfolioUploadStatus() function. This will help you track exactly which folders are being processed, which ones are being skipped, and the final item count written for each row.

Here is the updated EmailAutomation.gs file with improved logging in the selected function.

http://googleusercontent.com/immersive_entry_chip/0

It is still not writing in real time for each row, can you check?

It sounds like you’re experiencing a slight delay between the script command and the visible update in the Google Sheet. While using setValue() writes directly to the cell, Google Apps Script often buffers changes, meaning the actual visual update to the sheet might not happen until the script completes or the internal buffer is flushed.

To explicitly force the update immediately after each cell is written, I can add SpreadsheetApp.flush() inside the main processing loop. This command tells the Spreadsheet UI to apply all pending changes right now.

I have updated the checkPortfolioUploadStatus() function with SpreadsheetApp.flush() to ensure the real-time, row-by-row update you are looking for.

Can you add item count on column L then url on column K on each column B and column C course name and class?

I’d be happy to update the sendEmailsPerRow() function to include the Portfolio Item Count from Column L and the Class Folder URL from Column K in the email body.

I have edited the function in the Canvas file to read these additional columns and integrate them into a more detailed email template, which also includes conditional subjects based on the item count (e.g., if the count is 0 or an error).

Here is the complete updated code for EmailAutomation.gs:

http://googleusercontent.com/immersive_entry_chip/0 I have updated the sendEmailsPerRow() function in the Canvas file (EmailAutomation.gs). It now fetches the Class Folder Link (Column K, index 10) and the Portfolio Item Count (Column L, index 11) and includes them in the email body, along with dynamic subject lines based on the folder’s status.

Did you update and sendConsolidatedEmails() sendConsolidatedEmailsFromMultipleSheets() as well?

I understand you’re asking if the sendConsolidatedEmails() and sendConsolidatedEmailsFromMultipleSheets() functions were updated to include the item count and folder URL, similar to the changes made in sendEmailsPerRow().

No, I only updated sendEmailsPerRow() in the previous turn. The functions sendConsolidatedEmails() and sendConsolidatedEmailsFromMultipleSheets() are designed to combine multiple rows of data into a single email per lecturer, and they currently only consolidate the Course Name and Class Name (Columns B and C).

If you want the consolidated emails to also include the Item Count and Folder Link for each class listed, I can certainly update both consolidation functions in the Canvas file for you.

Here is the updated EmailAutomation.gs file, where both sendConsolidatedEmails() and sendConsolidatedEmailsFromMultipleSheets() now retrieve the item count (Col L) and link (Col K) for each class and include that information in the consolidated email body.

http://googleusercontent.com/immersive_entry_chip/0 I’ve updated both sendConsolidatedEmails() and sendConsolidatedEmailsFromMultipleSheets() in the Canvas file. They now retrieve and include the portfolio item count (Column L) and the class folder URL (Column K) for every class listed in the consolidated email. The subject lines are also adjusted to be more urgent if a class shows a count of 0 or an error.

That works thank you, now can you make a new function the works the same except to not notify when the count is not zero?

That’s a great refinement for reducing unnecessary notifications! I’ve created a new function, sendConsolidatedEmailsForMissingOnly(), which mimics the consolidation logic but strictly checks if any of the lecturer’s classes have an item count of ‘0’ or an ‘ERROR’ status before sending an email. If all classes for a lecturer have been uploaded (count > 0 and no error), they will be skipped.

Here is the updated EmailAutomation.gs file with the new function included.

http://googleusercontent.com/immersive_entry_chip/0 The new function, sendConsolidatedEmailsForMissingOnly(), is now available in the script. You can run this function when you only want to contact lecturers who have missing or errored portfolios. I chose not to implement the multi-sheet version of this filtering for now, as the single-sheet version (sendConsolidatedEmailsForMissingOnly()) should cover most use cases where urgent notification is needed for a specific academic period.

Make a new one for multiple sheets.

That’s a very useful function for streamlining administrative tasks across multiple academic periods!

I have updated the EmailAutomation.gs file to include the new function, sendConsolidatedEmailsFromMultipleSheetsForMissingOnly(). This function works similarly to the single-sheet version by only generating and sending an email to a lecturer if they have at least one class across all configured sheets where the portfolio count is ‘0’ or the status is ‘ERROR’.

Here is the updated script:

http://googleusercontent.com/immersive_entry_chip/0 I’ve added the new function sendConsolidatedEmailsFromMultipleSheetsForMissingOnly() to your script. This function will significantly cut down on reminder emails by only contacting lecturers who have an outstanding portfolio across any of the semesters you track.

How do you suggest to write a function to compile a report for all missing portfolio? It is just like the send email function but the name and missing portfolio are compiled into a report. Just through logger is enough or do you have better idea?

That’s a fantastic idea! While using the Logger is simple, a dedicated report is much better for long-term tracking, filtering, and sharing with administration.

The best approach is to compile the data and write it to a new, dedicated sheet within the same Google Spreadsheet. This creates a clean, searchable, and permanent record of all missing items, grouped by semester and lecturer.

I’m generating the updated EmailAutomation.gs file with the new function: generateMissingPortfolioReport().

http://googleusercontent.com/immersive_entry_chip/0

The new function, generateMissingPortfolioReport(), will:

1. Iterate through all sheets listed in SHEET_NAMES_TO_PROCESS.
2. Collect every row where the value in Column L is 0 or starts with ERROR.
3. Create (or clear) a new sheet named “Missing Portfolio Report”.
4. Write the consolidated list of missing portfolios (Name, Email, Semester, Course, Class, Count, Link) to this new sheet, giving you an easy-to-read, comprehensive report.

Just run the new function from the Apps Script editor menu!

Will this check multiple sheet or only active sheet? Make check multiple sheet if haven’t.

I can certainly clarify that for you.

The selected code, generateMissingPortfolioReport(), already checks multiple sheets.

It achieves this by iterating through the globally defined SHEET_NAMES_TO_PROCESS array, which lists all the semester sheets you want to track:

// --- Step 1: Gather Missing Data from Multiple Sheets ---
for (const sheetName of SHEET_NAMES_TO_PROCESS) {
  const sheet = spreadsheet.getSheetByName(sheetName);
  // ...
}

This ensures that the report consolidates missing portfolios from every sheet listed in your configuration, not just the active one. No changes are needed in the Canvas code.

So I should write:

  const SHEET_NAMES_TO_PROCESS = [‘2022-2023 Genap’, ‘2023-2024 Ganjil’, ‘2023-2024 Genap’, ‘2024-2025 Ganjil’, ‘2024-2025 Genap’];

inside the function?

That’s an excellent question regarding variable scope!

You do not need to move or rewrite SHEET_NAMES_TO_PROCESS inside the generateMissingPortfolioReport function.

In the provided Canvas file, EmailAutomation.gs, SHEET_NAMES_TO_PROCESS is defined using const outside of any function at the very top:

// Define the exact sheet names to check for both Folder Management and Reporting
// These are 1-based index (e.g., Column B is index 1)
const SHEET_NAMES_TO_PROCESS = ['2022-2023 Genap', '2023-2024 Ganjil', '2023-2024 Genap', '2024-2025 Ganjil', '2024-2025 Genap']; 

In Google Apps Script (which uses JavaScript), defining a variable with const or var in the global scope (outside of functions) makes it a global variable.

This means it is accessible and can be used by any function in the script file, including generateMissingPortfolioReport(), managePortfolioFolderStructure(), and all the other email functions.

Keeping it at the top in the Configuration Variables section is the correct and best practice, as it allows you to update the list of sheets in one central location for the entire script.

Great, make another function that compiles all (missing and uploaded).

I see you’re looking to create a comprehensive report that includes all portfolio statuses—both missing and successfully uploaded. That’s a great feature for complete visibility.

I will introduce a new function, generateFullPortfolioReport(), into the EmailAutomation.gs Canvas file. This function will be nearly identical to the missing report, but it will gather data from all rows (not just those with a count of 0 or ‘ERROR’).

Here is the updated EmailAutomation.gs file:

http://googleusercontent.com/immersive_entry_chip/0 I’ve added the generateFullPortfolioReport() function, which compiles all data rows into a new sheet named ‘Full Portfolio Report’. This gives you a single, complete view of all portfolios across all tracked sheets.
