JSON Formatter
Format, validate, and beautify JSON data
How It Works
- Paste or type your JSON data into the input textarea. The tool accepts any valid JSON string.
- Choose an action: Format beautifies the JSON with proper indentation. Minify compresses it into a single line. Validate checks whether the JSON is syntactically correct.
- The formatted or validated output appears instantly. Use the Copy button to copy it to your clipboard.
Frequently Asked Questions
What is JSON formatting?
JSON formatting (also called JSON beautification) takes raw, minified JSON data and adds consistent indentation, line breaks, and spacing to make it human-readable. This is essential for debugging API responses, editing configuration files, and understanding data structures.
Is my JSON data sent to a server?
No. All JSON processing happens entirely in your browser using JavaScript's built-in JSON parser. Your data never leaves your device — there are no server uploads or data storage.
What is the difference between Format and Minify?
Format adds indentation and line breaks to make JSON readable. Minify removes all unnecessary whitespace to produce the smallest possible JSON string, which is useful for reducing file size in production.
