In short: I wrote a tool to import Pinboard bookmarks into Standard Notes.
I care a lot about digital privacy and really appreciate the approach Standard Notes claims to take with my data. I started putting my bookmarks into the service instead of Pinboard. Pinboard is another fantastic service, but wanted to import my bookmarks into Standard Notes to have everything in one place.
So I wrote a tool to do the import! You can use it here.
It's not a terribly complicated piece of software—it transforms some JSON data into some other JSON data—but it was useful to me and I hope it's useful to someone else out there.
The code is open source if you want to give it a look.
