JSON Converter

Validate, pretty-print, minify and convert JSON to YAML, CSV and XML — all in your browser, nothing uploaded.

What you can do

Common JSON workflows, solved in one tool.

Validate & format

Paste unformatted JSON from an API and get indented, readable output — or an exact error message.

Minify

Strip all whitespace for storage or HTTP bodies. Perfect for config payloads.

Convert formats

Move between JSON, YAML (configs), CSV (tables) and XML (legacy systems) without manual work.

Notes on conversions

A few caveats so you're never surprised.
