Convert & export bookmarks

Which format do I want?

• CSV — columns for title, URL, folder, domain and date added. Opens in Excel, Sheets or Numbers, and both Notion and Airtable import it directly as a database.
• Markdown — folders become headings and nested lists. Drop the file into an Obsidian vault and every bookmark is a live link.
• JSON — an array of objects with the folder path as an array. The one to use if you're feeding bookmarks into a script or another app's importer.
• OPML — an outline format understood by outliners and most RSS readers. Useful if a chunk of your bookmarks are blogs you'd rather subscribe to.
• Plain URL list — for archiving tools, wget -i, or pasting into a bulk-import box.
• Bookmarks HTML — a rewritten bookmarks.html. Useful for exporting one folder as its own file, or for cleaning up an export that another tool mangled.

A note on dates

Bookmark exports carry an ADD_DATE per bookmark and browsers preserve it across imports, so the dates in your CSV can go back further than the browser itself. Sorting a spreadsheet by that column is the fastest way to see what you actually saved in a given year.
