How to turn off Google form responses with certain conditions

To turn off Google form responses after a certain number of responses, you can use the below Apps Script code:

function shutdownForm(maxResponses) {
  var form = FormApp.getActiveForm();
  form.setAcceptingResponses(false);
}

function onFormSubmit(e) {
  var form = FormApp.getActiveForm();
  var responses = form.getResponses().length;
  var maxResponses = 10; // Replace 10 with the maximum number of responses you want to allow
  
  if (responses >= maxResponses) {
    shutdownForm(maxResponses);
  }
}

To shut off the form at a specific date and time, you can use the following code:

function shutdownForm() {
  var form = FormApp.getActiveForm();
  form.setAcceptingResponses(false);
}

function scheduleFormShutdown() {
  var form = FormApp.getActiveForm();
  var shutdownDate = new Date("January 1, 2021 00:00:00"); // Replace with the date and time you want to shut off the form
  
  if (new Date().getTime() >= shutdownDate.getTime()) {
    shutdownForm();
  }
}
