I Built a JSON Formatter That Fixes Broken JSON with AI

Paste broken JSON, get valid JSON back. AI handles missing commas, unquoted keys, trailing commas, and comments.

Try it: jsonfix-lake.vercel.app

Three modes: Format and Validate, Minify, and AI Fix. The AI fix uses Claude to repair common JSON errors that break JSON.parse().
