I have a couple of documents in Google Sheets/Docs that, whenever they are changed by people they are shared with, I'd like to be notified (don't care if the difference of the change is sent, just "Change occurred" flag is sufficient).

Ideally, this would be tune-able by how large the edit was (e.g. filter out 1-character change) but I'm OK either way.

Can this be done with either a document I own and shared with someone; or a document they shared with me?


This is possible as well without an applet like in the other answer.

You can only set up notifications for yourself. You won’t get notifications when you make changes on your spreadsheet, but you’ll get notifications when others make changes.

  1. On your computer, open a spreadsheet in Google Sheets.

  2. At the top, click Tools > Notification rules.

  3. In the window that appears, select "when" you want to receive notifications. Notify you when:

    Any changes are made: Set notifications when someone makes a change to a spreadsheet.

    A user submits a form: Set notifications when someone fills out a form.

  4. In the window that appears, select "how often" you want to receive notifications. Notify you with:

    Email - daily digest: Send a daily summary of all changes.

    Email - right away: Send an email for every change.

  5. Click Save.

    this is for sheets only; no answer for docs. – Eric Bloch May 3 '18 at 19:05

We can setup manual triggers on the doc you want to follow changes for, using Google Apps script. By making the trigger execute after fixed time, we can monitor the changes in the doc. One way would be create a new backup sheet out of current sheet, and when next time the trigger is executed we check the current sheet with backup sheet, if there is any change, we can use MailApp to send mails.

There are automatic trigger as well but since the do not require user's consent before performing any actions, they have a lot of restrictions on them. Such as, automatic triggers are not allowed to send services that require authentication(MailApp).

Please follow these links for more info -

You can use an add-on like ezNotifications to enable this functionality for Google Docs.
