Identifying Form destination (Spreadsheet AND SHEET)

Question

FormApp.getActiveForm().getDestinationId()

give me the spreadshe

Answer 1

There is now a way to verify which sheet in a Google Sheets file with multiple linked forms corresponds to the current Form - through the use of Sheet#getFormUrl(), which was added to the Sheet class in 2017.

function getFormResponseSheet_(wkbkId, formUrl) {
  const matches = SpreadsheetApp.openById(wkbkId).getSheets().filter(
    function (sheet) {
      return sheet.getFormUrl() === formUrl;
    });
  return matches[0]; // a `Sheet` or `undefined`
}
function foo() {
  const form = FormApp.getActiveForm();
  const destSheet = getFormResponseSheet_(form.getDestinationId(), form.getPublishedUrl());
  if (!destSheet)
    throw new Error("No sheets in destination with form url '" + form.getPublishedUrl() + "'");
  // do stuff with the linked response destination sheet.
}

If you have unlinked the Form and the destination spreadsheet, then obviously you won't be able to use getDestinationId or getFormUrl.
