ummm, so you copy-paste from nov.el into an org buffer and then format would be maintained... interesting.

Thanks

I think it will be more practical for you to use pandoc:

With this command you can convert an epub format to org:

pandoc my-epub.epub -o my.epub.org

(https://pandoc.org)

You can also install calibre and convert your epubs to plain text from
there.

PS: And you can also open epubs in Emacs with the nov.el package
(https://github.com/wasamasa/nov.el) and copy whatever text you want
from there.
