I'm being asked to use a Google sheets document owned/edited by someone else. The document has macros that need to be run, but I'm hesitant to run them in my normal Google account as I'm not sure how much is possible with these macros. I understand that they can do a lot within the document itself, but I'm wondering if there is any risk of this document reading other files that I have access to. If necessary, I can create another Google account to use just for these files.
Anybody know what the biggest risk is here outside of tampering with the document itself.
