Hey everyone! I’m trying to set up a system for our school where parents can scan a QR code when they arrive, and it automatically updates a Google Sheet with their kid’s info. The sheet would be shown in the assembly hall so students know when their parents are here.
I’ve got the basics down:
Parents scan QR code at the entrance
QR code contains a link with the student’s details
Data should go into a Google Sheet
I’m comfortable with creating and publishing a script as a web app and passing variables through parameters. But I’m stumped on how to specify which Google Sheet to update.
Does anyone have experience with this kind of setup? I’m not a pro coder, but I can handle most scripts. Any tips or pointers would be super helpful! Thanks in advance!
As someone who’s implemented a similar system for a local community center, I can share some insights. The key is using Google Apps Script to create a web app that handles the incoming data and updates the specific sheet.
In your script, you’ll want to set up a doGet(e) function that processes the incoming parameters from the QR code scan. Then, use the SpreadsheetApp.openById() method to access your specific Google Sheet. You’ll need the sheet’s ID, which you can find in its URL.
For example:
var sheet = SpreadsheetApp.openById(‘your-sheet-id-here’).getActiveSheet();
sheet.appendRow([studentName, timestamp]);
This approach worked well for us, allowing real-time updates without manual input. Just remember to set appropriate permissions when publishing your web app to ensure data security.
One tip: Consider adding a simple caching mechanism to prevent duplicate entries if a QR code is scanned multiple times in quick succession. Good luck with your project!

Consider implementing a caching mechanism to prevent duplicate entries from multiple scans. Also, test thoroughly to ensure reliability during high-traffic periods, like school dismissal times.
hey there! i’ve done something similar for my kid’s soccer team. you can use the spreadsheet ID in your script to target the right sheet. it’s in the url when you open the sheet.
just make sure to test it a bunch before going live. we had some hicups with multiple scans causing duplicates. good luck with your project!
