Would love to know this as well. I have tried to do this but they seem to have very different and incompatible file types. If you just upload your note directly it will just come up as a document containing all sorts of coding in it (like if you open a Tomboy note with Word Pad).

If you copy and paste to google docs or Word then you lose your formatting. And my formatting is very important to me.

I just spent the afternoon getting about 80 of my notes into google docs in a manner which preserves my formatting. Very slow and painful process. And still have over a 100 to go but have parked these for now cause just do not have the strength to do that anytime soon. Hopefully someone will find a solution.

Anyway how I got them into google docs with formatting preserved was I synced with ubuntu. Then I had to go into each doc and copy and paste the text of the notes into google docs as new documents. Could not find any other way to get my docs there with formatting preserved.
