Convert Reveal.js Slides To Powerpoint

First off you want decktape:

% npm install -g decktape

Then you will want to serve your reveal.js slides so they’ve got a URI. Use this. If you’ve got a URL, then do this:

% decktape reveal http://localhost:8080/blahblah.html blahblah.pdf

And then convert it to a pptx with the online Adobe converter over here.
