I have this situation: every working day I have a Google Sheet where me and my staff enter some data. I want at certain date and time my staff to be blocked from editing that Google Sheet, so only the owner will edit it after that date/time.
The date is the name of the Google Sheet.
Is this possible? And if yes, how?
You need a combination of Time-driven triggers and the protect()-method of the Class Range can be used.
Your can find the full answer in a similar question that has been posted at https://stackoverflow.com/questions/31625064/locking-cells-in-google-sheets-at-a-specific-time.
You can apply the same method for all cells instead of particular ones.
