As part as my move away from Microsoft I want to import one of my Onenote notebooks into Joplin. I followed the video instructions and obtained my package file. Once I relaised I needed to change the exported package to .zip so Joplin could see it I was abloe to attempt import. Unfortunately I got an error as per screenshot.
There is someone else right now having difficulties importing from OneNote.
This is a link to that thread and in there I listed a few choices that you have that are programs that act as mere converters between Microsoft and markdown.
You can try using one of these apps to convert to markdown and then import into Joplin and see if you get better results.
