I want to add a date value when a new row is added in Google spreadsheet.

I have seen the script on Add a 'creation date' value when a new line is edited, but I was not able to modify the code to my needs.

Which changes do I need to do in that script?

In the question you are linking to, the date stamping happens when a new line is edited. If you want the date to be inserted immediately when a new line is added, simply replace EDIT with INSERT_ROW:

function onModification(event) {
  var sheet = event.source.getActiveSheet();
  if (event.changeType == "INSERT_ROW") { // <-- This is true when a new row is inserted

function fillEmptyRows(sheet) {
    var range = sheet.getRange(1, 1, sheet.getMaxRows(), 1);
    var firstColumnValues = range.getValues();
    for (var i = 0; i < firstColumnValues.length; i++) {
      if (firstColumnValues[i][0] == "") { // Column 0 is A
         firstColumnValues[i][0] = new Date();

The script must be installed as an event handler: Click Resources -> Triggers -> Add new trigger, select the onModification method and select On change from the right-most dropdown menu.

NOTE: This does not seem to work yet if you have opted in to the new Google Spreadsheets.

  • Does this work in the new Google Spreadsheets as well?

  • The script runs automatically when the spreadsheet is edited. Did you press the Run button in the script editor? Don't do that - it will give you the error you're seeing. I have a working example spreadsheet, try to add a couple of rows to it, and (after a second or two) the A column will display the current date. Commented Dec 19, 2013 at 20:55
