If a value is itself JSON-encoded text, recursively parse it into nested JSON instead of leaving it as a string.

Paste raw or minified JSON on the left and click Beautify to pretty-print it with clean indentation, or Minify to collapse it to the smallest valid form. The editor validates as you type and highlights matching brackets so you can navigate deeply nested structures quickly. It doubles as a JSON viewer and validator, and everything runs locally in your browser.
No. All parsing and formatting happens locally in your browser with JavaScript — your data is never sent to a server, so it works offline and is safe for sensitive payloads.
Beautify adds line breaks and indentation to make JSON human-readable. Minify removes every non-essential character (whitespace and newlines) to produce the smallest valid JSON — useful for reducing payload size in APIs and config files.
When a value inside your JSON is itself a JSON-encoded string (a stringified object within an object), deep unescape recursively parses those nested strings into real structure instead of leaving them as escaped text.
The most common causes are trailing commas, single quotes instead of double quotes, unquoted keys, or comments — none of which are allowed by the JSON specification. The error message points to the position where parsing failed.
