|  | (Perl) Google Sheets - Append Values to an Existing SpreadsheetAppends values to an existing Google spreadsheet. Note: This example requires Chilkat v11.0.0 or greater. 
 use chilkat();
$success = 0;
# 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..
$jsonToken = chilkat::CkJsonObject->new();
$success = $jsonToken->LoadFile("qa_data/tokens/googleSheets.json");
if ($jsonToken->HasMember("access_token") == 0) {
    print "No access token found." . "\r\n";
    exit;
}
$http = chilkat::CkHttp->new();
$http->put_AuthToken($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"
#     ]
#   ]
# }
