Question

How well does keynote convert MS office powerpoint files? A colleague prepares Powepoinr presentations and if they send them to me will I be able to edit the content and send it back to them?

Answer 1

There are numerous threads about this question, you might profit from looking at some of them.
Preategui, KN does open PP docs, unless something's wrong. If you could describe, as exactly as possible, what you do, and what happens, we can probably sort this out.
That said, back to the OP: converting from PP to KN or vice-versa is easy enough, but they don't always translate exactly - remember, they're different programs, differently written, with different capabilities. The simpler the presentation, the fewer the differences will be; the more bells and whistles (animations, transitions), the differences become greater. Be aware that fonts often cause problems: the standard Mac font set is not identical to the standard Windows font set, and some people might be using custom fonts. About the only way to be sure your Windows recipient will see a KN presentation exactly as it was constructed is if it's exported to QT, but that wouldn't suit your purpose at all.
If the editing you want to do is limited to text and other content, you shouldn't have too much of a problem. But I'd stay away from changing formatting, animations and transitions.
