Export a reveal.js presentation to LibreOffice (odp) or PowerPoint (ppt, pptx)

Question

How do I export a reveal.js presentation to LibreOffice (*.odp) or PowerPoint (*.ppt, *.pptx)?

It's fairly easy to export to PDF, but for my colleague's to reuse my slides (and mix them with their own), they need ODP or PPT. I will always stick with html slides (such as reveals.js) because it is git friendly.

Answer 1

Word 2013 can now edit PDF, so can LibreOffice Draw.

I'd try what happens if you open the PDF in either of these and then try to get to save as PPTX / ODP.
