Make Google Apps your own

Schema.org markup in Gmail

Use Schema.org markup to create interactive cards and buttons in Gmail. Emails with markup appear in Google Search results when users look for tickets, flights, and events. Your markup will also help Google Now bring users the right information at just the right time.

Sheets, Docs, and Forms add-ons

Add-ons are small apps that run inside Google Sheets, Docs, and Forms. After you write an add-on with Apps Script — a server-side JavaScript platform — you can publish it to our store for millions of Google Apps users (or just the users in your domain) to find and install.

Custom functions for Sheets

Google Sheets offers hundreds of built-in functions like AVERAGE, SUM, and VLOOKUP. When these aren’t enough for your needs, you can create your own custom function — say, to convert meters to miles — then use it in your spreadsheet just like a built-in function.

Make your own apps

Realtime collaboration like Docs

Use the Realtime API to give your users the power of Google Docs-style collaboration. All JavaScript. No server. No sweat.

Your web app in Google Drive

If your web app lets users edit files, integrate with us so that users can open files straight from Google Drive. Our store is a great place to get discovered.

Web apps built with Apps Script

Compose backend JavaScript code right in your browser, then pair it with client-side HTML, CSS, and JS and deploy it on our servers. All free.

Drive farther further

Save to Drive button

When you put a Save to Drive button on your website, users can save files from your server straight to their Drive accounts. It's as simple as the +1 button for Google+: just pull in our JavaScript and add 1 line of HTML.

APIs for Android and iOS

With Drive now part of Android and available in our client library for iOS, integrating Drive into your mobile app has never been easier. Simply read and write files and we’ll handle the details, including sync and offline support.

Google Picker

Google Picker is a "file-open" dialog for information stored in Google servers, including Google Drive, Google Image Search, Google Video Search, and more. Use our JavaScript in your web app to let users select their files or upload new ones.
