Creating a Google Classroom and maintaining it can be a bit hectic for so many students in a school. Say you are the moderator of your school and your task is to create 10 Google Classrooms for different teachers. Manually doing this can be a very hectic process, that’s where Google Apps Script comes in.
Using Google Apps Script, you can automatically create Google Classroom with the data in the Google Sheet, and paste the Class code in the Google Sheet.
