What is a JSON Formatter & Validator?

A JSON formatter takes raw or minified JSON data and reformats it with proper indentation and line breaks, making it easy to read, debug, and understand nested data structures. The validator checks that your JSON conforms to the JSON specification, catching common mistakes like trailing commas, single quotes, or unquoted keys — and pinpoints the exact location of each error. This tool processes everything locally in your browser, so your data is never transmitted to any server.
