@joshthor welcome to the forum.
Apologies if I have misunderstood you but in addition to exporting all your notes in bulk, if you right-click a Notebook and select Export > MD - Markdown you can export the entire contents as Markdown files (as well as other formats). Likewise if you right-click a single note in the note list and select Export > MD - Markdown you can export the contents of just that note as Markdown (as well as other formats).
