In this article, we are going to delve into the different solutions that will help you troubleshoot and get rid of this error.

Apart from that, we’ll also discuss what this error is all about and why it occurs in your code. Keep on reading!

What is “typeerror: cannot read property ‘getrange’ of null”?

The “typeerror: cannot read property ‘getrange’ of null” is an error message that usually occurs when you are trying to access a range that doesn’t exist or is not properly initialized.

In addition to that, this error typically occurs in Google Apps Script when a variable or object is null.

Meaning it doesn’t have a value assigned to it, and an attempt is made to call the getRange () method of that variable or object.

In a nutshell, you’re trying to access a range that doesn’t exist or isn’t assigned, resulting in an error message.

What is Google Apps Script?

The Google Apps Script is a scripting language developed by Google that is based on JavaScript.

It allows you to do new and cool things with Google Sheets, Docs, Forms, and Slides.

Aside from that, it allows you automate tasks and create custom functions to extend Google Sheets.

Why does this error occur?

This error was raised for some reasons, such as:

• When you have a typo or misspell the name of a sheet or range that you’re trying to access.

• When the script does not properly define or initialize the variable that represents the sheet or range, it may be null when the script tries to access it, resulting in an error message.

• When the sheet or range that you are trying to access doesn’t exist in the spreadsheet, the variable that represents it will be null, and the error message will be raised.

• When you are running a script that doesn’t have sufficient permissions to access the sheet or range, an error message may occur.

How to fix “typeerror: cannot read property ‘getrange’ of null”

Here are the different solutions you may use to fix the “typeerror: cannot read property ‘getrange’ of null” error message.

Solution 1: Check for typos in sheet or range names

If there’s a typo in the sheet name, the sheet variable will be null, and an error will be raised when you try to access the “getRange ()” method.

To fix this, we need to make sure the sheet name is correct.

For example:

function myFunction() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SampleSheet1');
  var range = sheet.getRange('A1:D50');
  Logger.log(range.getValues());
}

Solution 2: Initialize the sheet or range variables

You need to initialize the range variable only if the sheet variable is not null.

For example:

function myFunction() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SampleSheet1');
  var range;
  if (sheet) {
    range = sheet.getRange('A1:B10');
    Logger.log(range.getValues());
  }
}

Solution 3: Verify if the sheet or range exists

You can check if the sheet or range exists in the spreadsheet before trying to access it.

For example:

function myFunction() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SampleSheet1');
  var range = sheet ? sheet.getRange('A1:B10') : null;
  if (range) {
    Logger.log(range.getValues());
  }
}

Solution 4: Use the try-catch block with a loop

If you have a lot of ranges to access and wanted to handle the errors more elegantly, you can use the try-catch block in combination with a loop.

For example:

var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SampleSheet1');
var rangeNames = ['A1', 'B1', 'C1', 'D1'];
var values = [];
for (var i = 0; i < rangeNames.length; i++) {
  try {
    var range = sheet.getRange(rangeNames[i]);
    values.push(range.getValues());
  } catch (e) {
    Logger.log('Error: ' + e);
  }
}

Solution 5: Check for permissions to access the sheet or range

You can check if you have the necessary permissions to access the sheet or range.

For example:

function myFunction() {
  try {
    var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('SampleSheet1');
    var range = sheet.getRange('A1:D10
