"JSON to String" converts a JSON document — object, array, or primitive — into a JSON-encoded string literal. The output is the original JSON wrapped in double quotes, with all inner double-quotes escaped as \", backslashes as \\, and control characters properly escaped.
This is equivalent to calling JSON.stringify(JSON.stringify(parsed)) in JavaScript. It is sometimes called "double stringify" or "JSON-as-string" encoding. The output can be pasted as a string value inside another JSON document or used where a single string field must carry an entire JSON payload.

Common Use Cases
- Embedding a JSON payload as a string value inside a wrapper JSON document.
- Preparing JSON for storage in a database column that expects a plain string.
- Encoding JSON for inclusion in an environment variable or shell script.
- Debugging double-stringified JSON responses from APIs.
- Creating JSON test fixtures where a field value is a serialized JSON string.
Example Input and Output
A JSON object is converted into a single escaped string literal.
{
"name": "Alice",
"active": true
}"{"name":"Alice","active":true}"Privacy
All conversion runs in your browser. No data is uploaded to any server.

To go the other direction — decoding a JSON string literal back to its original JSON — use the Unstringify JSON tool.
