Welcome to the official repository for the ONLYOFFICE app for Confluence Cloud!

Edit, co-author, and manage office files right inside Confluence Cloud pages using ONLYOFFICE Docs. Open documents, spreadsheets, presentations, and PDFs from page attachments — edit them in-place and keep your Confluence content and files in sync.

• Open & edit inside Confluence: Launch ONLYOFFICE editors directly from page attachments.
• Real-time co-editing: Collaborate with colleagues using Fast and Strict modes, plus track changes, comments, and built-in chat.
• Wide format support: Edit and view popular office formats.

To be able to edit documents in Confluence Cloud, you will need an instance of ONLYOFFICE Docs (Document Server). You can install free Community version or scalable Enterprise Edition.

To install free Community version, use Docker (recommended) or follow these instructions for Debian, Ubuntu, or derivatives.

To install Enterprise Edition, follow instructions here.

Community Edition vs Enterprise Edition comparison can be found here.

Alternatively, you can opt for ONLYOFFICE Docs Cloud which doesn't require downloading and installation. To get ONLYOFFICE Docs Cloud, get started here.

Administrators can configure ONLYOFFICE integration app via the Manage Apps section in Confluence Cloud (Apps -> Manage Apps -> ONLYOFFICE -> Configure). On the configuration page, set up:

• Document Editing Service Address: The URL of the installed ONLYOFFICE Docs (Document Server).

• Secret key: Enables JWT to protect your documents from unauthorized access (further information can be found here).

• JWT Header: Name of the header to pass the JWT in, if you use a custom header in your server

In the Pages module, you can attach files to the created pages: open the right context menu, click on the Attachments item and upload a file from the device.

The uploaded file will appear in the Attachments list. To launch the editor, click Edit in ONLYOFFICE. The file opens in the same window. The changes made are saved in the same file.

Note: If a file is not supported by ONLYOFFICE, the integration will show an error message.

ONLYOFFICE offers different versions of its online document editors that can be deployed on your own servers.

ONLYOFFICE Docs packaged as Document Server:

• Community Edition 🆓 (onlyoffice-documentserver package)
• Enterprise Edition 🏢 (onlyoffice-documentserver-ee package)
