Google Apps Script overview

Google Apps Script is a rapid application development platform that makes it fast and easy to create business applications that integrate with Google Workspace. You write code in modern JavaScript and have access to built-in libraries for favorite Google Workspace applications like Gmail, Calendar, Drive, and more. There's nothing to install—we give you a code editor right in your browser, and your scripts are saved to Google Drive and run on Google's servers.

If you're new to JavaScript, Codecademy offers a number of JavaScript courses. (Note that these courses weren't developed by and aren't associated with Google.)

What can Apps Script do?

Apps Script is versatile. Among other things, you can:

• Add custom menus, dialogs, and sidebars to Google Docs, Sheets, and Forms.
• Write custom functions and macros for Google Sheets.
• Publish web apps — either standalone or embedded in Google Sites.
• Interact with other Google services, including AdSense, Analytics, Calendar, Drive, Gmail, and Maps.
• Build lightweight add-ons and publish them to the Google Workspace Marketplace. If you anticipate building large scale add-ons, refer to Build a Google Workspace add-on using HTTP endpoints.
