Exporting highlights from Kindle Personal Documents to a TXT file There are two main categories in Kindle App for iPad:


Books - contains books purchased from Amazon; highlights are available at https://kindle.amazon.com/your_highlights — it works fine for me.
Personal Documents - contains all other books; highlights are not available online.


So, I have book purchased at different source than Amazon and I would like to be able to export my highlights and notes to a text file (or any other common format). My approaches so far:


As far as I know, https://kindle.amazon.com/your_highlights is available for Books category and thus, for Amazon-purchased books only. There are no entries from "Personal Documents"
I cannot move my book from Personal Document to Books - there is no such option in Kindle App. There is no such option on Amazon's "Manage Your Kindle" site too.
There is no option to export all highlights. Kindle app has option to share a highlight via Facebook or Twitter, but there is no option for copy or export it.


I synced my book with Kindle Touch and highlights are synced successfully. But:


There is no export option in Kindle Touch too.
I am unable to read highlights content on my cpu. The file with highlights has extension .azw3r and contains relative references, for example: annotation.personal.highlight 283390 283606.
There are no entries in My Clippings text file (there are entries there but for non-synced books).


The question is: How can I export my highlights and notes from iPad Kindle App to a TXT or any other common file?

Note I'm using Windows but I put this question to Apple.SE since the root problem comes from iPad.
You can use Bookcision.Hope this helps.
