Sharing permission for Excel used as a back-end

I have a powerapp that's using excel as a backend. The file is stored in OneDrive. When I give specific permission to a user, I believe I have to give them access to both the powerapp as well as the backend data file(s), right? When it comes to the xlsx file, do I have to give the read/write access for them to write data through the app? Or just view is ok?

 

I'm weary about sharing the xlsx file with them because I don't want them editing the file directly through Excel online. I want them to do everything through the app. But, when I give them share access to the xlsx file doesn't it tell them in an email about the file, location, etc...?

 

Thanks!

If your PowerApps app reads/writes data to an Excel file then the user will also need read/write access to the Excel. It is possible for a user to bypass the PowerApps App and edit the file directly in OneDrive since you have to share it file with the user.

Seems like a security flaw that MS needs to fix asap. I suppose there's no need for PowerApps if users can bypass it and edit the file directly! Thanks 🙂
