I’m migrating from OneNote and sharing an alternative to the community Importer plugin.
The alternative is a utility called OneNote MD Exporter. Its creator (alxnbl) originally wanted to migrate to Joplin. The utility also has a raw Joplin export but I used the Markdown export option. Here is the utility’s Github repo: https://github.com/alxnbl/onenote-md-exporter
The community’s Importer plugin has a critical limitation for OneNote. It flattens all hierarchical structure, puts all non-text media into a single folder, and doesn’t link back to the non-text media. Basically I would have to re-create the structure and links after import, and makes the resulting import a manual re-do process.
Alxnbl’s Exporter utility re-creates OneNote’s hierarchical structure as parent-child folders, puts non-text media as a “Resources” folder at the same folder level, and embeds links to these resources in the markdown. I found this export much less manual re-do than the Importer method.
So I wanted to share this alternative method for migrating off OneNote. Hope it helps others!
P.S. I should have noted this Exporter’s markdown format displays correctly in Obsidian. It is Github format, as far as I can tell, but can be configured.
