My boss has been pondering the possibility of migrating us from Word and Excel to Writer and Calc. My concern, as someone who exclusively uses LibreOffice at home, is those edge-cases where another entity sends us a document that has some weird behavior that might not be properly replicated in LibreOffice.
I’ve had pretty good luck with SoftMaker FreeOffice in the past, although it’s closed-source.
They’ve apparently learned coding skills at the expense of social skills.
