(Go) 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.
