JSON Formatter
Format, validate, and beautify JSON data — instantly.
How to Format JSON
Paste your raw JSON into the input area and click "Format / Validate". The tool parses the JSON, validates it, and displays it with proper indentation. Choose between 2 spaces, 4 spaces, or tab indentation. Use the Minify button to compress JSON into a single line for production use.
Why Format JSON?
Formatted JSON is easier to read, debug, and understand. APIs often return minified JSON that's hard to parse visually. This tool helps developers quickly inspect API responses, configuration files, and data structures. It also validates your JSON to catch syntax errors.
Is This Tool Free?
Yes, 100% free. JSON is parsed in your browser using native JavaScript — nothing is uploaded. Works offline too.
