Hot to edit libre Office files on iPad

I’d like to edit documents (mainly ods and odt) that I use everyday on my macbook during my workday when I’m on the move. And doing it smoothly.

I have all the documents I use in iCloud. The idea is very simple: to be able to modify files in the iPad and see the changes afterwards seamlessly on my computer and vice-versa.

Quite disappointed to see the lack of app in the App Store to do the job.

I’ve tried Collabora office, but find it complicated to work with.

Also numbers itself but saves the files in numbers format, not libreoffice format.

Anybody who had tried something useful for doing this job?

Thank you very much.

[ I guess there must be a lot of people out there using the iPad for doing more things like working than just shopping, social networking or watching movies.]
