@Jeff_Hager I also considered this script (https://ctrlq.org/code/19854-list-files-in-google-drive-folder) - but i’m afraid that I’m not at a level where I get it to work. When calling the script (like =listFilesInFolder(“zswzs8hL8toQmzds1Iof6svWoCW-zwdfsd”) I’m told that I don’t have permissions. ‘You do not have permission to call DriveApp.getFoldersByName. Required permissions: (https://www.googleapis.com/auth/drive.readonly || https://www.googleapis.com/auth/drive) (line 8).’
I tried the add-on you mentioned but it is verified so you cannot use google sign inf
Thx for trying to help me
