Just a suggestion:

If you download Kindle Mate (kmate.me), you can import your Kindle highlights to your PC and export them as a text file. Then you could make a script that parses this file line by line and saves it as a csv-file. Then use Anki csv-import.

EDIT: fixed the link.

Thanks for the tip. Unfortunately, kmate.me is PC only and I'm on a mac.
