Gists This is a sample script for converting A1Notation to GridRange and vice versa using Google Apps Script without any scopes. A1Notation and GridRange are often used with Sheets API. I have posted a sample script for converting A1Notation to GridRange before. Ref But, in that case, I used the method of Spreadsheet service (SpreadsheetApp). By this, in order to use the script, it is required to authorize the scopes. In this sample script, A1Notation can be converted to GridRange and vice versa with no scopes.
