Is there a way to insert an automatic "last edited" timestamp in the footer of a Google Document?

I would like to make sure that time stamp is on the document when I print. I figure out how to enter a "today" time stamp but need a script to pull "last edited" and, if possible, the user that last edited.

  • Seems impossible... although a script could be used to update a footer, there is no trigger "when edited" for Google Documents.

Yes, there is. Use file.lastModifyingUserName and file.modifiedDate.


function lastEdited() {
  var doc = DocumentApp.getActiveDocument();
  var id = doc.getId();
  var file = Drive.Files.get(id);
  var footerSection = (doc.getFooter())?doc.getFooter():doc.addFooter();
  var userName = file.lastModifyingUserName;
  var date = file.modifiedDate;
  var text = '[Last edited by ' + userName + ' on ' + Utilities.formatDate(new Date(date), 'GMT+5', 'YYYY/MM/dd hh:mm') + ']';
  var p = footerSection.insertParagraph(0,text);


  1. To use the above script you should enable the Google Drive Advanced service as is described in - https://developers.google.com/apps-script/guides/services/advanced


  • Where does this script go?

  • @Rubén - I still only see an available event type of "On Open" which would update the document only when someone opens it the next time, right? Or am I missing something?

  • @idean This Q/A isn't about triggers in Google Docs. Please post a new question.
