Auto delete old entries from Google Spreadsheet submitted using forms

Auto delete old entries from Google Spreadsheet submitted using forms


Following is a script that can be set (triggered) to auto deletes old entries every day from Google Spreadsheet submitted using forms:

Insert the following script in your spreadsheet project using script editor:


function DeleteOldEntries() {
  
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  //give your sheet name below instead of Sheet1
  var sheet = ss.getSheetByName("Foglio1");
  
  var datarange = sheet.getDataRange();
  var lastrow = datarange.getLastRow();


  var currentDate = new Date();
  var oneweekago = new Date();
  oneweekago.setDate(currentDate.getDate() - 7);
    
  for (i=lastrow;i>=2;i--) {
    var tempdate = sheet.getRange(i, 1).getValue();
    
    if(tempdate < oneweekago)
    {
      sheet.deleteRow(i);
    }
  }
}



The above script will delete rows (entries) that are one week old, you can change the duration in it as per your requirement.


If you are not familiar with writing scripts and don't know where to start from then have a look at the following link:

  1. Hello Kishan,
    I'd like to know, how this script can be modified to delete all entries that are older than 2 hours ?
    I tried it with using time(); but had no luck at all... Could you please help me?

    Thanks,

  2. I was wondering why you were counting down in the for loop, but I see why now. Counting up from 1 has some kind of bug where it's skipping rows for deletion. Thanks for the post.

  3. Does this delete the entire row or just the data within the row?
