Google Apps Script to sync from Spreadsheet to Calendar

script.gs

/*
  This script needs to be bound with a Google Spreadsheet.
  It needs to have a header row of the form: title | start | end | description
  The script then generates calendar entries for every row below.

  For example, the sheet could have the following entries (displayed in csv format):

  Title,Start,End,Description
  Test 1,27.02.2024 11:00:00,27.02.2024 15:00:00,Hallo 1
  Test 2,28.02.2024 15:00:00,28.02.2024 17:30:00,Hallo 2
  Test 3,26.02.2024 13:00:00,26.02.2024 16:00:00,Hallo 3

/**
 * number of rows in the header
 */
const offset = 1;

/**
 * first sheet
 */
const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0]

/**
 * Creates calendar entries for each row in the associated sheet
 */
function create_calendar_entries_from_sheet() {
  const rows = sheet.getSheetValues(1+offset,1,sheet.getLastRow()-offset,sheet.getLastColumn());
  for (const row of rows) {
    const [title, start, end, description] = row;
    try {
      const event = CalendarApp.createEvent(title,start,end,{description});
      console.log(`Created event "${event.getTitle()}" (ID: ${event.getId()})`)
    } catch(e) {
      console.error("Could not create event:");
      console.error(e)
