Assigning elements to an array in Google Apps Script can greatly enhance your scripting capabilities

I'm having an issue with my Google (Apps) Script that is connected to a Google Spreadsheet.

Every part of the script works perfectly, except for one line:

headers[0] = headers[0] + ":";

If I remove this line, the script runs smoothly. But adding it causes the script to fail.

I've initialized the array beforehand in the following way.

var s = SpreadsheetApp.getActiveSheet();
var headers = s.getRange(1,1,1,s.getLastColumn()).getValues()[0];

I am trying to figure out what's causing the issue with element assignment and how to resolve it.

Any assistance would be greatly appreciated.

Answer №1

This test function is quite straightforward:

function open() {  
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var headers = sheet.getRange(1,1,1,sheet.getLastColumn()).getValues()[0];
  Logger.log('Array of headers: ' + headers);
  Logger.log('First header: ' + headers[0]);
  headers[0] = headers[0] + ":";
  Logger.log('Modified header: ' + headers[0]);
}

It runs smoothly for me as shown here: http://prntscr.com/58a6fx.

I encounter no errors, so I suspect the problem may be more complex than just this line. When tested in a new script bound to a spreadsheet with some header values, it should execute without any issues.
