There are two issues to consider here:
- Exporting from Keynote to PowerPoint Mac: Keynote can do this, but
you have to be aware that some additional work is necessary: some
included images, especially those used as background for table cells,
may appear as big black blobs in PowerPoint; other images will be
converted to bitmap format during the export, so that you'll lose the
professional appearance provided by Keynote; list tags (bullets,
etc.) will change size and vertical positioning when viewed in the
PowerPoint version. All this needs to be fixed manually from within
PowerPoint.
- Converting from PowerPoint Mac to PowerPoint Windows: you need to
make sure that the fonts used in your presentation are available on
Windows; you need to make sure that the codecs for the animations in
your presentation are available on Windows (for example that
QuickTime for Windows is installed). For some reason it seems that in
some occasions PowerPoint Windows refuses to play the animations
included in the PowerPoint Mac file, so that the animations will have
to be included again one by one on the Windows machine. In this
respect, it seems that whether the animations are included inside the
PowerPoint file or put alongside it as separate files does matter.
Microsoft has put online instructions on the compatibility between
the Windows and Mac versions of the Office suite, making them appear
as really different applications (so that, in effect, you shouldn't
expect an Office Windows file to be readable flawlessly by Office Mac
and the other way round). See below a copy of another post that I
made to this list earlier this year (translated to English).
Feeling at ease with Keynote and not willing to spend time learning
to use PowerPoint, I tend to prepare all presentations in Keynote
and, when absolutely necessary, convert them to PowerPoint. However,
that's never an immediate process (count, say, half a day of work for
complete conversion from Keynote to PowerPoint). Another conversion
that I haven't seriously tried yet is from PowerPoint to OpenOffice
Impress.
Equations, in addition, may represent another significant challenge
when converting, from PowerPoint Windows to Keynote. In that case,
I'd say a full day of work for the complete conversion of a 30-slides
presentation.
