You cannot convert a Flash file (.swf) into a PowerPoint file (.ppt). However, you can embed an .swf movie into a PowerPoint presentation. To do that, you need to open your PowerPoint application, go to the options and select Show Developer tab in the ribbon. Then you can go to the Developer tab -> and press More controls button that looks like a tilted hammer, search and select Shackwave Flash object. On the slide, input the size that you want the flash movie to be, right click on it and choose Properties. In the Movie zone type the exact location of your Flash file (it can also be an Internet URL).
