With Aspose.Words, you can convert ODT to DOC and EPUB file format. Please check the following code example.
Document doc = new Document(MyDir + "input.odt");
doc.Save(MyDir + "20.1.doc");
doc.Save(MyDir + "20.1.epub");
Currently you cannot convert an EPUB file to Word format using Aspose.Words. We suggest you please read the following article.
