Reads multiple ranges from a Google Sheets spreadsheet in one GET request.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

// See Global Unlock Sample for sample code.

// This example uses a previously obtained access token having permission for the 
// Google Sheets scope.

// In this example, Get Google Sheets OAuth2 Access Token, the access
// token was saved to a JSON file.  This example fetches the access token from the file..
