JSON Formatter
Format, minify, and validate JSON in your browser.
How to use JSON Formatter
Best for
- Pretty-printing JSON responses, config snippets, and copied payloads.
- Minifying JSON before saving or sharing compact text.
- Catching basic JSON syntax errors before using the data elsewhere.
Steps
- Paste JSON into the input box.
- Choose Format for readable indentation or Minify for compact output.
- Read any parse error before copying the output.
Notes
- JSON parsing checks syntax, not whether the data matches your application schema.
- Do not paste secrets into browser tools unless you are comfortable handling them locally.
FAQ
Does this validate JSON?
It validates JSON syntax by parsing the input, but it does not validate a schema or business rules.
What does minify do?
Minify removes unnecessary whitespace while keeping the parsed JSON value the same.
