Universal Office Converter (unoconv) is a command line tool to convert any document format that LibreOffice can import to any document format that LibreOffice can export. It makes use of the LibreOffice's UNO bindings for non-interactive conversion of documents. For practical reasons we mention LibreOffice, but OpenOffice is supported by unoconv as well.
