Retrieves All Named Ranges in Spreadsheet as a1Notation
This is a sample script for Google Apps Script (GAS). This script retrieves all named ranges in Spreadsheet. The names and range of the retrieved named ranges are output as the keys and the values of JSON object, respectively. The sample output is {"name1": "Sheet1!A1:B2", "name2": "Sheet2!B1:C2",,,}. The name of named range has to be only one in the spreadsheet. This was used.
Sheets.Spreadsheets.get() of Sheets API can retrieve all named ranges. But the retrieved range is the grid range. So in this sample script, the grid range was converted to a1Notation. The main part of this sample script is here.
