Are you aware of the limitations of the PDF format? It was originally supposed to be a final "container" format, and in many cases does not convert well to other, more editable formats. So yeah, if you deliver a PDF made with InDesign and your customer demands Powerpoint, you're kind of out of luck. I know that third-party conversion tools do exist, and that Adobe Acrobat itself does save out PPTX these days, but the product blurb from Adobe says outright:
NEW Spend less time reformatting
When you convert your PDF to PowerPoint, your formats are saved, too — so you'll spend far less time reformatting bulleted text, tables, objects, and master layouts.
But that really does imply to me "you'll spend time reformatting bulleted text, tables, objects, and master layouts... well... everything."
If my client needed a revision-heavy workflow and the final product was a Powerpoint presentation, I'd start in Powerpoint. Not in InDesign. (And I'd be grumbling the whole time, yeah, but it'd be better than trying to duct-tape a file-conversion workflow together.)
So it's a limitation, not something I'm doing wrong? hm... thanks for your input
I agree with Joel. If the deliverable is Powerpoint, work in Powerpoint. The workflow you're attempting will entail much more work and compromise the final result.
Some other things you may want to consider in this thread.
I represent Recosoft. We make ID2Office (http://www.recosoft.com/products/id2office). This exports/converts InDesign CS5-CC 2014 files to Word, PowerPoint and Keynote formats. There is no need to go via the PDF route. You can view the Youtube video I've posted below how it converts the file:
