JSON

How this JSON Deserialize Online works

This parser converts stringified or escaped JSON strings back into properly formatted JSON objects. It handles common scenarios including double-quoted strings containing escaped JSON, API responses with nested serialization, and logs with escaped special characters.

The algorithm first removes outer string wrapping, then processes escape sequences (\n, \t, \\, \") before attempting to parse the result as JSON. Successfully parsed content is pretty-printed with proper indentation for readability.

All processing runs locally in your browser. This tool is particularly useful for debugging API responses, parsing log entries, and working with JSON data that has been serialized multiple times.
