|  | (Excel) Google Sheets - Append Values to an Existing SpreadsheetAppends values to an existing Google spreadsheet. 
 '  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..
Dim jsonToken As Chilkat.JsonObject
Set jsonToken = Chilkat.NewJsonObject
success = jsonToken.LoadFile("qa_data/tokens/googleSheets.json")
If (jsonToken.HasMember("access_token") = False) Then
    Debug.Print "No access token found."
    Exit Sub
End If
Dim http As Chilkat.Http
Set http = Chilkat.NewHttp
http.AuthToken = jsonToken.StringOf("access_token")
'  To append values to an existing spreadsheet, our HTTP request body will
'  contain JSON in the format of a "ValueRange".  For example, the spreadsheet we'll be
'  adding to in this example looks like this:
'   '  The JSON ValueRange for the cells in the above spreadsheet is:
'  {
'    "range": "Sheet1!A1:B5",
'    "majorDimension": "ROWS",
'    "values": [
'      [
'        "Item",
'        "Cost"
'      ],
'      [
'        "Wheel",
'        "$20.50"
'      ],
'      [
'        "Door",
'        "$15"
'      ],
'      [
'        "Engine",
'        "$100"
'      ],
'      [
'        "Totals",
'        "$135.50"
'      ]
'    ]
'  }
'  This example will append 6 cells (3 rows / 2 columns).
'  We'll be appending the following:
' 
'  "Paint", "$100"
'  "Brakes", "$100"
'  "New Total", "$335.50"
' 
'  The range of cells we'll be appending is A1:B5
'  Therefore, the ValueRange JSON we'll be sending in our POST body is:
'  {
'    "range": "Sheet1!A1:B5",
'    "majorDimension": "ROWS",
'    "values": [
'      [
'        "Paint",
'        "$100"
'      ],
'      [
'        "Brakes",
'        "$100"
'      ],
'      [
'        "New Total",
'        "$335.50"
