Thanks a lot for this!
Me too, but I miss some Wikidpad-features, especially the link view tree (Link tree view in the left sidepanel) which is clearer than the graph view. I migrated because the development of Wikidpad stopped, and I’m afraid that I can’t use it any more at one time or another.
I have my old Wikidpad database with about 5000 notes still in use, and migrate manually, when I update an item.
Your script seems great. I’m not a programmer- I really would appreciate a smoother and better documented version.
