Real-time
co‑editing

Edit Word, Excel and PowerPoint files together in your browser.

How it works

How collaborative editing works

1. Open in browser

Double-click any Office file. It opens in a browser-based editor with the full Word, Excel or PowerPoint feature set.

2. Edit together

See colleagues' cursors live. Comments, suggested edits and chat are all in-document. Conflicts are resolved automatically.

3. Save with full history

Every change is versioned. Revert by paragraph, by file or by user. Export to PDF or original Office formats anytime.

Use cases

Multiple authors edit a long proposal at the same time, comments resolved inline, exported to PDF for the client.

FAQ

Frequently asked questions

Will my Word formatting break?
No. The editor is built on OnlyOffice, which renders .docx, .xlsx and .pptx files with the same engine as Microsoft Office, including macros, conditional formatting and embedded charts.
How many people can edit at once?
Dozens of concurrent editors per document, tested with 25+ simultaneous users. Larger sessions are available on enterprise plans.
What happens if two people edit the same paragraph?
Changes are merged automatically using operational-transform algorithms. Conflicts surface in the comments sidebar for manual review when needed.
Can I work offline?
Yes, use the desktop sync client to edit files locally in Microsoft Office or LibreOffice. Changes sync and merge when you reconnect.
Do my macros still work?
Most VBA macros run inside the editor. Complex automations that depend on the Windows shell are best handled in desktop Office via the sync client.
Can guests edit a document?
Yes. External guests can be invited as commenters or editors per document, with optional expiry on their access.
