Since there hasn't been much progress in the last months and from time to time some I have to export formats not supported by writer2epub, I thought it might be meaningful to collect alternatives to this plugin. So far I'm aware of

- odt-import in calibre,
- writer2latex (http://writer2latex.sourceforge.net/), which provides an export-to-epub function and requires java,
- eLAIX (http://extensions.libreoffice.org/extension-center/elaix/releases/4.1), which seems to have some problems with new versions of libreoffice, and
- amanuensis (http://amanuensis.pagesperso-orange.fr/).

Hi

ODTImport is a new Sigil plugin making use of writer2xhtml (Java). It can output to EPUB2 and EPUB3 formats.
Another Programm is alkinea

What license does it use?
For EPUB or AZW I've found saving in DOCX and importing that into the calibre editor can yield better results (marginal to quite a bit) than converting ODT. And if there are any glitches KG usually fixes them quick smart, same day if you run calibre from source, otherwise it'll be in next release, which is rarely more than a fortnight away.

'OSX iWork Pages' can export to Epub. Not 'amazing' but quick and hastle free.
The Calligra Office Suite can export to epub. There is also an application dedicated to writing books, Author. Don't know about the quality of the epubs, but the software is open source and part of the KDE project.
Libreoffice 6 now seems to include a filter for exporting to epub.
Pandoc is very efficient and has a lot of input format but it does not have a graphical interface (command line only)

LibreOffice V.6 has a very good export in ePub, both ePub2 and ePub3.
Under the menu File>Export As… you can find this option.

The next version of Writer2ePub for LibreOffice will be just an helper for composing a good ePub, but the creation of the ePub itself will be done by LibO.

Thanks for your interesting in W2e
