So I used to be a huge MS Office file format geek because of my work with Apache POI (https://poi.apache.org/ https://poi.apache.org/). I spent some time playing around with LibreOffice API's to try to use them for file format conversion. I feel like LibreOffice/OpenOffice file compatibility with MS Office peaked in the early 2000's. The last time I tried to load a Word doc in LibreOffice a few years ago, it looked very janky. About the same as it did in 2004. Sadly, I still receive 2 or 3 Office attachments a week. So MS Office compatibility is still very relevant.
