Open and edit Office files on your Chromebook
On your Chromebook, you can open, edit, download, and convert many Microsoft® Office files, such as Word, PowerPoint, or Excel files.
Important: Before you edit Office files, check that your Chromebook software is up to date.
Insert Office Add-ins into Excel Online
Important: New name for apps for Office - Office Add-ins. We are currently updating our products, documentation, samples, and other resources to reflect the platform name change from "apps for Office and SharePoint" to "Office and SharePoint Add-ins". We made this change to better distinguish the extension platform from Office apps (applications). While these changes are taking place, the dialogs and messages you see in your application might be different than what you see in this article.
Maybe this information will help you.
Thanks for your patience and understanding
