JSON Formatter
Format, validate and minify JSON online. Paste raw JSON and get a readable, indented version.
How to use?
Paste the JSON into the left field. Use Format to indent it, or Minify when you want it compacted. Any syntax error gets flagged in red by the validator.
Format and validate JSON instantly
JSON is the lingua franca of APIs, yet on a single line with no spaces it turns into an unreadable blob. This formatter takes raw JSON and hands back an indented, organised version where you can see the structure, the nesting and every key in place. Far easier to read and debug.
It doesn't just prettify, it validates too. If there's a stray comma, a missing quote or a badly closed brace, the error gets flagged so you can fix it. Need the reverse? You can minify, stripping spaces and line breaks to make the JSON compact before sending it.
All processing runs in the browser, so your JSON (even with sensitive data) never leaves your device or lands on any server.
