Google Apps Script is a scripting platform developed by Google for light-weight application development in the Google Workspace platform. Google Apps Script was initially developed by Mike Harm as a side project while working as a developer on Google Sheets. It is based on JavaScript 1.6, but also includes some portions of 1.7 and 1.8 and a subset of the ECMAScript 5 API.
