It seems like a lot of european countries have started becoming more concerned with digital sovereignty and some have begun enforcing using open formats like ODF / ODS
I’m struggling to find support though. A lot of software seems to open ODS files but force the XLSX format on save.
I’d expect something like OnlyOffice to have support since it’s used by the French government and the government of their German neighbours is enforcing ODS usage + there should be a reasonable library they could import to make it work without a large overhead
Yeah, I quite like libreoffice on the mac but I’m not always on my mac. I kind of thought one of the European cloud storage providers might offer support for editing too but they auto convert to Microsoft formats during edit and that just seems like it would be more error prone. And on an iPhone I only found one app that would edit in place, everything else views or converts to Microsoft formats
