Add-on video library

  • These videos demonstrate how to build add-ons for Gmail and Google Slides, extending their functionalities with custom features.

  • The Gmail add-on example showcases automating expense reports by integrating with Google Sheets, while the Slides add-on introduces the concept of creating progress bars.

  • Each video provides a walkthrough of a sample application, offering developers a practical starting point for exploring specific platform features.

  • Source code and detailed instructions are available through accompanying codelabs and documentation, facilitating hands-on learning and implementation.

The following videos show a variety of example add-on applications. Each video generally walks through a short sample app to give you a jump start in trying specific platform features.

Expedite expense reports with Gmail add-ons

Add-ons let you extend Gmail as well as integrate functionality from your app into Gmail's user interface. In this video, learn about the ExpenseIt! Gmail add-on, helping working professionals process receipts directly from their inbox into a Sheet, creating one place to complete their expense reports. Build the add-on piece-by-piece with its corresponding codelab.

This feature is also described in the blog post "Gmail add-ons framework now available to all developers".

Make progress (bars) with Slides add-ons

Google Slides doesn't have progress bars. Wouldn't this be a useful feature for both presenters as well as audiences? In this video, developers learn how to implement simple progress bars by using the Slides service to create an add-on. With this add-on, users can enable or hide progress bars in their presentations. The code and a full description of this add-on can be found in the documentation as a Quickstart example.
