Any way of converting ppt or odf to beamer or org?

If you are interested I can share with you some VBA code I have developed to do just that. You can load it as a macro and run it. It will give you a txt file of the same name as the ppt and dump the pictures as png files. It will also show the number of the slide it came from. I want to eventually take the VBA code and create a stand alone application but the time is not there yet.

' this code extracts text from PPT(X) and saves to latex beamer body

There is another project for ppt to beamer conversion. I have used it and the major downside was that a 20 slide ppt with about 8 bullets per slide became an over 200 slide beamer. I also had to manually fix about 20+ LaTeX errors per slide. And there are some difficulties with graphics.

I used this about 4 years ago and I was able to convert quickly the 72 ppt slide shows for a semester course in an afternoon.
