OpenDocument (ODF) is the native file format of LibreOffice, and is supported by many other apps too. Here's am update about the ODF Toolkit, which can be used to create ODF files: https://blog.documentfoundation.org/blog/2021/12/16/two-odf-toolkit-releases-in-a-row/
@libreoffice I like to use open formats wherever I can but I've always wondered why support in other languages is so poor.
@levi You can work with ODF files in various other languages: http://www.opendocsociety.org/tools/odf-tools/ – But if something is missing, it's because nobody has stepped up to work on it! We're a volunteer-driven, community open source project (with very limited resources). We'd appreciate more help: https://whatcanidoforlibreoffice.org
