How it works

  1. Drop or paste a bookmarks export in HTML, CSV, JSON, Markdown, or plain URL-list format.
  2. The converter detects the input format and combines everything into one consistent bookmark list.
  3. Choose the output format you need: browser bookmarks HTML, CSV, JSON, Markdown, or URLs.
  4. Download or copy the converted result without uploading your bookmarks anywhere.

Convert bookmark exports without losing the useful structure

Browser bookmark exports are not one universal thing. Chrome, Firefox, Edge, and Safari usually export importable bookmarks as Netscape-style HTML. Chrome's internal profile backup is JSON. Spreadsheet workflows often want CSV, while notes apps usually want Markdown.

This converter auto-detects the common shapes and translates them into one internal tree. HTML uses the shared TabGroup Vault bookmarks parser. CSV uses title,url,folder columns. JSON accepts simple {title, url, children} trees and Chrome's roots backup format. Markdown input reads standard [title](url) links and uses headings as folder names.

The tradeoff is that some formats carry less information. A plain URL list has no folder structure. Markdown can preserve folders only if headings are present. If you need a high-confidence backup that can round-trip through browsers, export bookmarks HTML first and keep that original file untouched.

Frequently Asked Questions

How do I export bookmarks from Chrome?
Open Chrome's bookmark manager, use the three-dot menu, and choose Export bookmarks. Chrome downloads a standard bookmarks HTML file. Drop that file here to convert it to CSV, JSON, Markdown, or a plain URL list.
Can I convert Chrome's Bookmarks backup file with no extension?
Yes. Chrome's profile backup named Bookmarks is JSON, even though it often has no file extension. Paste it or drop it here and the converter will read the roots, folders, and URL nodes.
Does folder structure survive round-trips?
HTML, JSON, and CSV with a folder column can preserve folder paths. Markdown and plain URL lists are less strict, so folder recovery depends on headings or the absence of folders. For the safest round-trip, use bookmarks HTML or JSON.
Excel mangles my URLs. Why?
Spreadsheet apps sometimes auto-format long URLs, dates, or special characters. This tool writes CSV with a UTF-8 BOM so Excel and Sheets detect the encoding more reliably. For best results, import the CSV as text/UTF-8 instead of double-clicking it.

Converting bookmarks is a symptom.

Tab chaos is the disease. TabGroup Vault keeps working sessions as restorable snapshots instead.
