What’s new for Excel add-ins developers in 2021 


We’ve been amazed by the breadth and depth of the solutions our community has built on Excel over the years. When it comes to extending Excel, the Office Add-ins platform makes it easy for you to get your data into the hands of Excel users across Windows, Mac, and on the webAs Tristan Davis mentioned in his blog post on January 27 this year, our team is invested in helping you build your own capabilities into software used by millions of people worldwide.  

This year, we’re focused on the following to further enhance your development experience: 

  1. Building upon a powerful foundation through the WebView2 Control. 
  2. Contextual ribbon tabs and shortcut keys to enhance the user experience of your data.  
  3. New APIs like AddFromBase64 to simplify your development. 
  4. Enabling users to collaborate with your data in Excel on the web through Microsoft Teams. We’re investing in making the dialog and single sign on APIs work seamlessly in that context and ensuring that your add-ins can be fully deployed. 
  5. Improving performance, specifically for custom functions 
  6. Building communityinspired patterns and practices such as the Open in Excel and the share state and run code on doc open patterns. Patterns and Practices is an open-source community program where anyone can jump in and help deliver content and code samples for the Office Add-in developer community.
