Beautify, minify, validate, and explore JSON data. Syntax highlighting and tree view included.
The JSON Formatter beautifies, minifies, and validates JSON, with a collapsible tree view, diff mode, and JSONPath queries — a fast, private way for developers to read, debug, and clean up JSON data.
Beautifying adds consistent indentation and line breaks so nested JSON is easy to read. Minifying does the opposite — stripping whitespace to make the payload as small as possible.
Yes. The validator checks your JSON against the spec and points out syntax errors like missing commas or brackets, so you can fix them quickly.
No. All formatting, validation, and querying happen locally in your browser — your JSON never leaves your device, which matters for sensitive data.
JSONPath is a query syntax for extracting specific values from a JSON document, similar to how XPath works for XML. The tool lets you run JSONPath queries against your data.
