How to automatically delete rows that contain a date with more than 3 days offset to the past from now?

Question

I am trying to get a script going that will automatically delete rows with a date over 3 days old (4 days on)

I found this script that I was hoping to be able to adap

Answer 1

It will be much much faster if your rows are in order of date, newest at the top and you delete all the rows at once and not one at a time.

function deleteOldData() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("CallHub1");
  var datarange = sheet.getDataRange();
  var lastrow = datarange.getLastRow();
  var values = datarange.getValues();// get all data in a 2D array

  var currentDate = new Date();
  var daysago = new Date().setDate(currentDate.getDate() - 3);
  var yearago = new Date().setDate(currentDate.getDate() - 365);


  for (i=lastrow;i>=2;i--) {
    var tempdate = values[i-1][0];// arrays are 0 indexed so row1 = values[0] and col3 = [2]
    if(tempdate < daysago)  {
      if(tempdate < yearago)  {continue;}
      sheet.deleteRows(1, i);
      break;
    }
  }
}
