How to use the JSON Stringify and Unstringify
- Enter or paste your input in the box (or set the options, if the tool needs no input).
- Adjust the options to match what you need — the result updates as you type.
- Copy the result or download it, and keep editing if you want a different outcome.
What does this tool do?
Use this when you need to embed JSON inside another JSON value, a code string or an environment variable. The input is validated first, then escaped with the right backslashes. Switch direction to unescape a double-encoded string.
Everything runs in your browser, so nothing you enter is uploaded or stored.
Why use it?
- Free, with no sign-up and no limits.
- Instant results as you type.
- Private — your data stays on your device.
Example
Input: {"a":1}
Result: "{\"a\":1}"
