JSON Formatter

Format, validate, beautify or minify JSON instantly — with clear error messages that point to the exact line and column.

Your formatted JSON will appear here…

How to use

  1. Paste your JSON into the text area.
  2. Choose Format to pretty-print with 2-space indentation, Minify to compress it to one line, or Validate to check it without changing it.
  3. If the JSON is invalid, the error message tells you exactly which line and column has the problem.

Privacy note: everything runs in your browser — your JSON is never uploaded or stored.
