MS Office Online Server as document editor in Nextcloud

About Office Online Server

As Microsoft explains in their documentation:

Office Online Server is an Office server product that provides browser-based file viewing and editing services for Office files. Office Online Server works with products and services that support WOPI, the Web app Open Platform Interface protocol.

Office Online Server includes Word Online, Excel Online, PowerPoint Online and OneNote Online. Office Online Server runs on dedicated servers or a virtual machine, and thus fits in a on-premises environment with Nextcloud.

Collaborative editing is supported, allowing multiple users to work together in the same document, seeing what the other users are doing.


From within Nextcloud, Office Online Server is well integrated like our other online office solutions, allowing users to directly view and edit documents without having to open other tabs or windows. Our sidebar is available so users can comment, share, see previous versions and even chat during editing. They can also drop a office document in a Talk chat room and edit it with the other participants during a call.


The Office Online Server option allows enterprises to migrate users from cloud services or locally installed office applications to a web based work flow, fully on-premises and under control of the IT department. Users get the interface they are familiar with, and great document compatibility.

Administrators can install the app and get started now.
