Frequently Asked Questions
Escaped JSON occurs when a JSON object is serialised as a string value inside another context — for example, logged to a file, stored in a database column, sent as a form field, or returned inside a JSON string field. Double quotes get prefixed with a backslash (
\"), making the output human-unreadable and unusable until it is unescaped.
Common situations: API responses where JSON is returned as a string value (e.g.
{"data":"{\"id\":1}"}); payment gateway transaction logs; PHP json_encode() inside another json_encode(); JavaScript JSON.stringify() called twice; database-stored JSON; copied terminal/debug output.
Double-escaped JSON happens when already-escaped JSON is escaped again, producing strings like
\\\"id\\\". This tool handles multiple levels — it repeatedly unescapes until it reaches valid parseable JSON.
No. All processing happens entirely in your browser using JavaScript. Nothing you paste is transmitted anywhere. It is safe to use with sensitive payloads, API keys, or private data.
