{} JSON Formatter

Format, validate, and minify JSON with adjustable indentation and key sorting — paste messy or minified JSON and get clean, readable output instantly.

How to Use This JSON Formatter

Paste or type JSON into the input pane and click Format to pretty-print it with your chosen indent (2 spaces, 4 spaces, or tabs), or Minify to strip it down to a single line. Enable "Sort keys" to alphabetize object keys, which makes it easier to spot differences between two JSON payloads.

Invalid JSON is flagged with a clear error message so you can find and fix the problem quickly. Use "Copy Output" to grab the formatted result, or "Sample" to load example JSON and try the tool out.
