(C# UWP/WinRT) Google Sheets - Update (Set Values in a Range)

Sets values in a range of a spreadsheet. This example will demonstrate by first getting a range, then changing some values in the JSON, and then HTTPS PUT the changes back to the Google Sheet.

Note: This example requires Chilkat v9.5.0.76 or greater.

//  This example requires the Chilkat API to have been previously unlocked.
//  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..
