FWIW and like it or not, libreoffice is the best or only way to do some of the things it does. I don’t actually use it directly as an office suite really ever. But I do use tools that use its libraries, like unoconv, or that depend on it for other things, like Nextcloud. It’s a beast and a burden, but if you need to deal with Office documents of unknown provenance, programmatically, it’s a valuable and relevant set of tools.
