How to Import Mac Keynote Files into Microsoft PowerPoint
Users of Keynote may already know that they can open PowerPoint files in the iWork application. Sadly, the reverse is not true.
Importing a Mac Keynote file into Microsoft PowerPoint means that you must first prepare the Keynote presentation file. This is easily done – begin by opening the file on your Mac in Keynote.
To convert in Keynote '08, go to File > Export.
On this screen, you can convert the file to PowerPoint – choose the PPT tab (PPT is the file extension for PowerPoint documents) and then Next. Following this, select your intended file location to save the converted document and click Export.
In Keynote '09, open File > Save As... give your file a name and expand the box with the down arrow. Next tick the Save copy as: box, and select PowerPoint Presentation. Click Save to complete.
Your export is now complete, and you can now open your Mac Keynote presentation in Microsoft PowerPoint. However, you might notice some differences.
