📖 About JSON Formatter

JSON (JavaScript Object Notation) is a lightweight data interchange format. This tool helps you validate JSON for syntax errors, beautify it with proper indentation, and minify it by removing all unnecessary whitespace. All processing happens in your browser — no data is ever uploaded.
