I had been using Laverna for a while. I had a few dozens of notes taken, but in the end I didn't stick with it. Cleaning up my Dropbox folder (where Laverna syncs), I found my old notes. I wrote this small script to export them to Markdown before cleaning up the folder. The script needs to be run inside the Laverna Dropbox app folder. I didn't care to preserve the notebook hierarchy, so the script doesn't process the contents of the notebooks folder.
