Google Apps Script Tutorial: Create a Custom Menu to Change Cell Background Color in Google Sheets

Welcome to our Google Apps Script tutorial! In this video, we'll guide you through the process of enhancing your Google Sheets experience by creating a custom menu that lets you easily change the background color of selected cells with a single click.
Our code is simple but powerful, consisting of two functions:
onOpen(): Triggered when you open a Google Sheets document, this function sets up a custom menu labeled 'Custom' in the Google Sheets user interface.
backGroundColor(): Executed when you select the 'Color' option from the custom menu, this function automates the process of changing the background color of the currently selected cells. You can customize the color by modifying the provided hex value (e.g., '#FFFF00' for yellow).
We'll provide step-by-step instructions on how to use and adapt this code for your specific needs. Whether you're organizing data, highlighting important information, or just adding a splash of creativity to your spreadsheets, this tutorial will help you unlock the full potential of Google Apps Script. Stay tuned, and let's get started!

Thank you for this tutorial, is it possible to match the background color of a cell with another one? (when using setbackground, it gives the error message as I don't have permission to call setbackground)
