How can I migrate from google keep to asciidoc?

Hello everyone. I am trying to figure out how can I migrate my notes from Google keep to asciidoc.

First Method
I tried the following method. I have downloaded all my google keep notes from Google Takeout but all keep notes are downloaded without google keep label hierarchy(All HTML files in the same folder). I can convert all HTML files to plain text but without google keep label hierarchy, there is no reason to do this. How can I get google to keep note files with google keep label folder hierarchy?

Is there any practical way to achieve this?
