By the way, LibreOffice also supports OOXML, so… do with that what you want.

Yes, from the article:

LibreOffice currently handles ODF files perfectly and handles OOXML files better than Windows 365 and other software handle ODF files. Poor handling of ODF files “forces” users towards OOXML files, thus pushing them towards lock-in and protecting a business worth around $30 billion (because lock-in functions like a pair of handcuffs).
