根据日期删除 Google 表单提交

Question

I'm trying to remove responses from Google forms that are older than a set age. I have a script to do this for the sheet, but this does not remove the responses from the form. Removing all responses from the form is not an option as I need to retain the responses not older than the set age. This is the script which works on the sheet, which I need an equivalent for on the form.

script working on sheet

function DeleteOldEntries() {
  
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  //give your sheet name below instead of Sheet1
  var sheet = ss.getSheetByName("Sheet 1");
  
  var datarange = sheet.getDataRange();
  var lastrow = datarange.getLastRow();


  var currentDate = new Date();
  var oneweekago = new Date();
  oneweekago.setDate(currentDate.getDate() - 1095);
    
  for (i=lastrow;i>=2;i--) {
    var tempdate = sheet.getRange(i, 1).getValue();
    
    if(tempdate < oneweekago)
    {
      sheet.deleteRow(i);
    }
  }
}

Answer 1

You need to write a script to delete the response from the Form same as you write for the spreadsheet. Please refer this link for deleting form single response by Id

Answer

I've created a Form and I managed to delete the submits older than a week. There are a few methods that you have to use to achieve that goal:

Steps

• Open your Form . You can use getActiveForm if you are using an Apps Script project contained in a Form document. Otherwise, use openById or openByUrl
• Get all the responses with getResponses
• Get the timestamp of each with getTimestamp
• Compare the two timestamps with a simple if statement
• When the condition is true
  • Get the id of the response with getId
  • Delete the response with deleteResponse

Code

function deleteSubmissions(){

  var oneweekago = new Date();
  oneweekago.setDate(oneweekago.getDate() - 1095);

  var form = FormApp.getActiveForm() // FormApp.openById() | FormApp.openByUrl()
  var responses = form.getResponses()

  for (var i=0; i<responses.length; i++){
    var r = responses[i]
    var responseTime = r.getTimestamp()
    if (responseTime > oneweekago){
      var id = r.getId()
      form.deleteResponse(id)
    }
  }
}
