I'm Sidd, and I built JSONEdit because my JSON routine was spread across too many tabs: one site to format, another to diff, a throwaway script to pull out one field, another site to convert to YAML. Many of those sites also upload your data to a server, which isn't great when it's a production API response. JSONEdit puts it all in one place, and everything runs locally in your browser: ✏️ JSON Editor: text and tree views stay in sync. Double-click to edit in the tree, and undo works for tree edits too. ⚖️ Compare: a structural diff, so key order and whitespace never show up as changes. 🔍 Query: JSONPath and JMESPath testers with live results. ✅ Validate: JSON Schema (draft-07, 2019-09, 2020-12), with the exact path of every error. 🔄 Convert: YAML, CSV, XML, JSON Patch, Base64, JWT decoding. 🎭 Protect: mask emails, phones and card numbers before sharing, or generate realistic mock data. 🔗 Share: read-only links that expire in 90 days. This is the only feature that sends data anywhere, and only when you click it. It's free with no account. Tip: open any public API directly with jsonedit.com/json-editor?url= I'd love your feedback. What JSON chore should I build a tool for next?
