Co-editing is where office staff judge the whole system. This page describes the daily reality honestly — what feels the same as Google Docs, what feels slightly different, and what staff should expect in week one.
Every demo shows two people editing one document smoothly. Your staff will ask harder questions: will my Word files break, will it feel slow, can two of us really work in one quotation at once? The honest answers are mostly good news — with a few differences worth knowing before migration day, not after.
Real-time co-editing genuinely works. What differs from Google Docs is the feel around the edges, not the core job.
Open a document from Nextcloud and OnlyOffice loads it in the browser with a ribbon that any Word user recognises in seconds. When a colleague opens the same file, you see their name, their cursor and their typing live. Comments, suggestions and tracked changes work the way office staff expect. There is nothing to install on staff PCs — it is all in the browser — and the phone and tablet apps handle viewing and light edits comfortably. For letters, quotations, invoices, reports and everyday spreadsheets, this is a complete replacement for the editing part of Google Workspace or Microsoft 365.
OnlyOffice works natively in Microsoft formats — docx, xlsx and pptx are its home formats, not an import it struggles with. In practice this is the best compatibility you will find outside Microsoft itself: documents that clients send open correctly, and documents you send back open correctly in their Word and Excel. Complex Word documents with heavy formatting, and spreadsheets with advanced Excel functions or macros, are the honest edge cases — macros in particular do not run the way they do in desktop Excel. The one-week rule after migration: keep desktop Word or Excel available for the two or three genuinely complex files, and let the other 95 percent live in the browser.
Every time a document is closed, Nextcloud keeps the earlier versions. The practical effect: the fear of "someone ruined the file" disappears. Staff can open the version list, preview yesterday’s quotation, and restore it in two clicks. Teach this in the first training session — it converts more sceptics than any feature list, because everyone in every office has lost work to a bad save exactly once and remembers it.
Tell staff three things before launch: it will feel 95 percent familiar; the first day is for learning where buttons moved, not for judging the system; and genuinely strange files should be reported, not suffered in silence. Offices that brief honestly keep their staff. Offices that promise "exactly like Google, but free" spend month one apologising for a few seconds of load time.

Watch Full VideoVery unlikely. OnlyOffice uses the Microsoft formats natively, so normal documents, letters and spreadsheets open and save cleanly. Keep an eye on files with heavy macros or extreme formatting in the first weeks — those are the known edge cases, and desktop Word or Excel remains the fallback for them.
Yes, that is normal co-editing and it works with live cursors, names and comments, much like Google Sheets. Just note the free community edition has a simultaneous-connection ceiling — fine for small offices, worth planning around for large ones.
For reading, approving, commenting and small corrections, yes. For building a large spreadsheet or a long formatted report, nobody enjoys that on any platform, including Google’s. The desktop browser is the real workplace; the phone is the companion.
