What is JSON Formatting?
JSON formatting (or “pretty printing”) adds consistent indentation and line breaks to make JSON data readable. This tool parses your JSON, validates it, and outputs a clean, indented version. All processing happens in your browser — your data never leaves your machine.
Keyboard shortcuts: Ctrl+Enter to format, Ctrl+Shift+M to minify.
