JSON Formatter
Format, validate, and beautify JSON data with syntax highlighting.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is used extensively in web APIs, configuration files, and data storage.
How to use this tool
Paste your JSON into the input field. The tool will validate it in real-time and highlight any syntax errors. Click 'Format' to pretty-print with your preferred indentation, or 'Minify' to compress it into a single line. Use the copy button to copy the result to your clipboard.
Common use cases
Debugging API responses, cleaning up configuration files, validating JSON payloads before sending them to a server, converting minified JSON to a readable format, and preparing JSON data for documentation.
