Paste a JSON value and convert it into an escaped string literal. All inner double-quotes, backslashes, and control characters are properly escaped so the result is safe to embed as a string inside another JSON document.

What is JSON to String Converter?

"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.

How to Use JSON to String Converter

1

Paste your JSON into the input area or click "Load Sample"

2

The encoded string literal appears instantly on the right

3

Click "Copy" to copy it to your clipboard or "Download" to save it

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.

JSON input
{
  "name": "Alice",
  "active": true
}
String literal output
"{"name":"Alice","active":true}"

Privacy

All conversion runs in your browser. No data is uploaded to any server.

Tip

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

Frequently Asked Questions

What is the difference between JSON to String and JSON Stringify?

JSON Stringify (JSON.stringify) converts a JavaScript value to a JSON text string. JSON to String goes one step further: it calls JSON.stringify twice — first to produce the compact JSON text, then again to wrap that text in a JSON string with escaped inner quotes. The result is a string literal you can embed inside another JSON document.

Why are the inner quotes escaped with backslashes?

JSON strings must use double quotes for delimiters. Any double quote that appears inside a string value must be escaped as \" to avoid breaking the JSON structure. This tool handles all required escaping automatically.

How do I reverse this operation?

Use the Unstringify JSON tool. Paste the escaped string literal and it will parse the outer string and then parse the inner JSON to restore the original structure.

Is my JSON sent to a server?

No. All conversion happens in your browser using JSON.parse and JSON.stringify. Your data never leaves your device.

What if my JSON is invalid?

The tool validates JSON before converting. If the input is invalid, it shows a parse error. Use the JSON Fixer tool to repair common JSON issues first.
