bookmarks-to-json

bookmarksToJSON is a no-dependecy, Regex-based pure JS function that takes in the HTML-style code of the bookmarks files exported by browsers like Chrome and Firefox, and converts them into JSON / JS object format with a recursive tree structure.

Bookmarks, folders and subfolders are nested using a children property on the folders.
