How to Lock a Sheet
in Google Sheets
Open Google Sheets and click on the sheet tab at the bottom that you want to lock.
Click on the small downward-facing arrow on the sheet tab and select "Protect sheet" from the dropdown menu.
In the right-hand "Protected sheets and ranges" sidebar, click "Set permissions."
Choose whether you want to restrict editing to specific users or only allow certain people to make changes.
Click "Done" to apply the lock, preventing unauthorized edits to the sheet.
You can edit or remove the restrictions anytime by revisiting the "Protected sheets and ranges" settings.
