Austria's military just ditched Microsoft for open-source LibreOffice

It's not because it's better. If you just need a basic excel/doc alternative, maybe.

As soon as you need some more complex excel calculations, LibreOffice falls flat.

Good luck getting formatting to look correct in a .doc file opened by Microsoft Office 99% of the time.

Librecalc is fine and I would argue most people don't use the arcs advanced features of MS Excel.

The reason it's incompatible with MS Office is because MS doesn't use a consistent standard or the iso standard. Theyve done this as a counter measure to alternatives.

librecalc shuts down for me all the time on small simple documents on different OSs and hardwares. I don't know how to work with it. I'm using Onlyoffice for editing and Tad for reading csv/xlsx files now.
