Hi
I was using api key to read from excel.
Same api key was used to write to an excel but an error is thrown.
Write Cell: Google.Apis.Requests.RequestError
Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See การรวม Google Sign-In เข้ากับเว็บแอปของคุณ | Google Sign-In for Websites | Google Developers. [401]

how to write to an excel?
