Understanding JSON Format
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 in virtually every modern web API, configuration file, and data storage system.
This tool helps you format (beautify) messy or minified JSON with proper indentation for readability, validate JSON structure by catching syntax errors with descriptive messages, and minify JSON by removing all whitespace for production payloads. All processing happens in your browser — your data never leaves your device.
