Docs about the import/export database

[iBicha]

Hello everyone!

I recently started working on yt2alt - a tool to export data from Youtube (Subscriptions, Watch history, Liked videos, Watch later, Recommended videos and Playlists) and I would like to add support for NewPipe.

I'm wondering if there's any documentation about the format to make sure a produce a valid db to be imported (I know it's zipped sqlite database - but not much else about the format)

Thank you!

I settled with supporting only subscriptions for NewPipe iBicha/yt2alt#3
But if anyone can shed some light on importing more things from the list (Watch history, Liked videos, Watch later, Recommended videos and Playlists) please let me know.
Thanks!
