What's New in Collabora Office

25.04.9

March 4, 2026

Hi everyone - happy new year! Yes, I know it's March - but we've had a bit of a longer break than usual and I didn't get to tell you that yet :) In this version we've made some accessibility improvements - we hope the app should be much easier to use if you're using a screen reader now. We've also built this with fixes and features from Collabora Online 25.04.9. Finally, we're resuming our normal release schedule - the next version will be in around a month's time - thanks very much for using Collabora Office!

Excellent

Using this on an iPad Air I was able to view edit and save existing xlsx files that I have saved on Dropbox.
These files were originally made with Libre Office on Linux and the compatibility was 100%
Nice!

Can’t copy formulas

Nothing I can do will allow me to copy formulas on my IPad. I asked ChatGPT for help and after a half hour and several screen shoots I gave up after ChatGBT said it looks like a bug in the IPad verison

Great Potential but has problems

The biggest issue I have is the “disconnected from server” message and resultant unresponsive state. This happens even editing a local odt file.
Removing the app from memory and restarting seems to fix the problem.
It would be nice if the developers could fix this issue.
There are a few quirks which are annoying but once you figure out how to deal with them the app works well.

Not sure about this one

looking for replacement for SmartOffice, not on App Store any longer. Drawn to this app through the open source MS office alternative Libre office website as a way of reading their documents on an iPad. Also a fan of the privacy policy - apparently not gathering any information. However, as soon as I opened the app, it went directly to my Files folder, trying to access everything I had in there. Documents I wanted to open in SmartOffice were stored in SmartOffice or were accessed such as dropbox. It did not go searching my iPad for anything it could open. Ultimately not sure about this privacy claim. deleted the app.

Initial review

I’m also surprised why this has such a low rating. So I tried Opendocument Reader and OOreader. Both were terrible with the latter worse (viewer only, no editor) than the former (viewer and editor). Collabora Office displays the spreadsheet correctly with tab names or correct order, highlighted tabs display correctly, split screens also. I downloaded this to mainly view my ODS files while traveling but I might venture to do some editing and see how this app works. So far it’s great.
