Are you familiar with LibreOffice? Are there any advantages that OnlyOffice has over other open source spreadsheets?

Sibling comment nailed my feeling on this: the UI of onlyoffice is modern and clean. To add on, it gives me a feeling of confidence that it can round-trip files back and forth from excel more reliably; a lot of people on my team also use excel and we need to exchange workbooks, so that was what prompted me to move on from LibreOffice when I lost confidence that files would be able to remain pretty stable going back and forth.

I’m a very occasional and casual user of office programs. Mostly I don’t use them.

What I like about OnlyOffice over LibreOffice is the UI. I like how it’s one program that can open all the documents rather than a collection of different programs as well. It feels clean, simple, and modern.

Same thing
