Google Apps Script

Google Apps Script is a JavaScript cloud scripting language that provides easy ways to automate tasks across Google products and third party services.

With Google Apps Script you can:

• Automate repetitive business processes (e.g. expense approvals, time-sheet tracking, ticket management, order fulfillment, and much more)
• Link Google products with third party services (e.g. send custom emails and a calendar invitation to a list from a MySQL database)
• Create custom spreadsheet functions
• Build and collect user inputs through rich graphics interfaces and menus (e.g. a company could power an internal application for purchasing office supplies where users could shop via a customized menu interface)
