Pandoc will also write opml. A quick test indicated all input formats
may not be useful. I didn't get any output when I read a docx file, for
example. I was hoping the headers would appear as topics.

An export to opml from Mellel works that way, but I always feel odd
recommending Mellel. On the one hand, it is the One True Word Processor
before which all others grovel in despair. On the other hand, if you are
in a Word frame of mind you probably won't have much fun with it.

I know Mellel very well and its combination with Bookends is perfect. But Mellel does not provide any ressources section like Scrivener does.
