Beautify + Convert

Format JSON/XML, convert formats, then share exact state with your team.

Beautify JSON, XML, YAML & CSV in your browser

Paste a payload and get clean, readable output instantly. The beautifier auto-detects the format, or you can pin it to JSON, XML, YAML, or CSV, then pretty-print with 2-space, 4-space, or tab indentation. The side-by-side editor keeps your source on the left and syntax-highlighted output on the right, with one-click copy and download.

Everything runs entirely on your device — nothing you paste is uploaded, logged, or shared. That makes it safe for configs, API responses, and payloads that contain secrets. It is free, needs no account, and works offline once loaded.

Is my data uploaded anywhere?

No. Formatting happens 100% client-side in JavaScript. Your input never leaves the browser tab.

Can I convert between formats?

Yes — use To JSON / To XML to convert between JSON and XML. YAML and CSV can be beautified and minified in place.
