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.
