# Office

Nextcloud supports two office solutions for collaborative document editing:

**Nextcloud Office** (powered by Euro-Office)  
The default office solution built into Nextcloud. Enables real-time collaborative editing of text documents, spreadsheets, and presentations with high-fidelity rendering. Requires a Euro-Office Document Server.

**Collabora Online**  
A fully supported alternative based on the Collabora Online Development Edition (CODE). Available as a self-hosted server or as a built-in app. Enterprise users can use the more stable Collabora Online Enterprise through a [Nextcloud support subscription](https://nextcloud.com/enterprise/).

Both solutions support dozens of document formats including DOC, DOCX, PPT, PPTX, XLS, XLSX, ODF and many more.
