AI Google Apps Script Debugger

Fix Google Apps Script errors instantly

Quick Apps Script Debug Examples (click to try)

My script fails with: “Cannot read property ‘getRange’ of null” when editing a sheet.
I get “TypeError: Cannot call method ‘appendRow’ of undefined” when adding a row to another sheet.
My Apps Script keeps timing out when processing large Google Sheet datasets.
My time-based trigger doesn’t always run my function as expected.

Fixed Apps Script Code AI Debugged


function onEdit(e) {
  // Check if e and e.range are valid
  if (!e || !e.range) return;

  var ss = e.source;
  var sheet = ss.getSheetByName("Sheet1"); // Use correct sheet name

  if (sheet) {
    var range = sheet.getRange(e.range.getRow(), 1);
    range.setValue("Edited!");
  } else {
    Logger.log("Sheet not found.");
  }
}


function addRowToOtherSheet() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("Data"); // Be sure this name matches your tab!

  if (!sheet) {
    Logger.log("Sheet 'Data' not found.");
    return;
  }
  // Append row safely
  sheet.appendRow(["Name", "Value", new Date()]);
}


function processLargeData() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var data = sheet.getDataRange().getValues();

  for (var i = 0; i < data.length; i++) {
    // Do fast batch processing, avoid .setValue in each loop!
    data[i][1] = "Processed"; // Example: bulk update
  }

  // Write back all at once
  sheet.getRange(1, 2, data.length, 1).setValues(data.map(function(row){return [row[1]];}));
}


function myTimedTrigger() {
  try {
    // Your logic here
    Logger.log("Trigger running at " + new Date());
  } catch (error) {
    // Log detailed error for troubleshooting
    Logger.log('Error: ' + error.message);
    MailApp.sendEmail(Session.getActiveUser().getEmail(), 
      "Script Trigger Error", 
      "There was an error in your scheduled Apps Script trigger: " + error.message
    );
  }
}

// To reset the trigger (run once manually if needed)
function createTimeTrigger() {
  ScriptApp.newTrigger('myTimedTrigger')
    .timeBased()
    .everyHours(1)
    .create();
}

Code Breakdown
The error occurs when your script tries to access a range from a null sheet object. The fix makes sure the e object and the desired sheet both exist before calling getRange(), avoiding runtime errors if the user is on the wrong sheet or if the trigger is missing parameters.

Code Breakdown
This error occurs when the sheet variable is undefined—usually because the sheet name is misspelled or the tab does not exist. The new code checks the sheet exists before calling appendRow and logs a message if not.

Code Breakdown
Apps Script times out if you write to the sheet one cell at a time. This fix updates data in a cached array, then performs a single bulk write back, which runs much faster for large data sets.

Code Breakdown
This fix adds error catching to your timed trigger, logs errors, and even notifies you via email if a problem occurs. There's also a helper to recreate the trigger in case it stops running (which sometimes happens in Apps Script).

Pro Tip

Paste the full error message and describe which line it occurs. Instead of "my script fails", try "I get 'Cannot read property getRange of null' in my onEdit trigger on line 4".
