I have view-only access to a Google Sheet. Is there any way I can set up an email notification whenever there is any change to this Google Sheet?
(Right now, Tools > Notification Rules is greyed-out.)
No, there definitively isn't such a possibility if you have view-only access. The workaround would be to use
IMPORTRANGE formula to import the whole sheet into your spreadsheet and then set up an email notification based on changes of your sheet. Note that due to
IMPORTRANGE limitations you could experience up to a half hour delays.
Try this, it may help you:
