I have a spreadsheet, and I have shared it with 50 people for the editor role. I have written some js codes in app script but unfortunately, someone removed my code and the spreadsheet has been affected for the reason.
I need a solution so that no one views or accesses my app script code who has an editor role.
There are several ways to protect a script from users who have editor access to the spreadsheet, depending on the nature of the script.
If the script runs when a time-driven trigger fires, it can be implemented as a stand-alone script project that nobody else has access to.
If the script contains UI code such as dialog boxes or sidebars, you would have to rewrite the script as an add-on.
The third option is to implement the script as a library with only a few short stub functions in the script project that is bound to the spreadsheet, and the rest of the code in the library.
two projects. One project is bound to the "target spreadsheet"; this may or may nor contain code and any editor can view that code. But the second project (which need not be bound to a spreadsheet at all) references the "target spreadsheet" by ID. Editors of the target spreadsheet won't easily find the second project, so the code is effectively hidden from them.
