bulk add ao3 bookmarks?

[tozka]

Hi all! I'm a Pinboard newbie, and I'm trying to add all of my AO3 bookmarks using the bookmarklet on fangirling.net. However, I have 900 bookmarks on AO3 alone. It is VERY slow-going, even with all the automated stuff set up in the bookmarklet.

Is there a way to bulk add my bookmarks? Maybe an export+import combo?
