Why developers use this JSON editor

Built to cover the everyday JSON workflow in one place — validate, reshape, visualize, and hand off data without switching tools.

🔍

Click-to-copy path breadcrumbs

Switch to Tree view and hover any node to copy its exact path (e.g. $.users[2].email) — great for writing queries or bug reports.

💾

Export to 5 formats

Download your document as JSON, YAML, CSV, XML, or an Excel workbook without leaving the page.

📋

Multi-tab workspace

Keep several documents open at once. Tabs persist in local storage, so your work survives a page refresh.

🔒

100% client-side

Parsing, validation, and formatting all happen in your browser. Nothing is uploaded, logged, or stored on a server.

📈

Instant chart view

Arrays of numbers or objects are automatically visualized as bar, line, or pie charts — handy for eyeballing API responses.

🔗

Shareable links

Generate a URL that encodes small JSON snippets directly, so you can share an example without a paste bin.

Frequently asked questions

Is my JSON data uploaded to a server?

No. Every tool on this site runs entirely in your browser using JavaScript. Your data is never sent to a server, logged, or stored anywhere except your own browser's local storage.

Is this JSON editor really free?

Yes — completely free, with no sign-up, no usage limits, and no watermarks.

Can I use this JSON editor on mobile?

Yes, the layout is fully responsive. A larger screen makes editing complex documents easier, but every feature works on phones and tablets too.

What makes this different from other online JSON editors?

It bundles features most free JSON editors leave out: click-to-copy JSON paths, a JSONPath/JMESPath query tester, JSON-to-TypeScript/Java/Go generation, a schema generator, and export to five formats.
