How it works
How to use the JSON Unescape
Paste text
Paste the escaped JavaScript string.
Pick options
Choose whether to add surrounding quotes or escape non-ASCII characters (where relevant).
Copy the result
Use Swap to go the other direction.
What gets unescaped
For JavaScript, backslash, quotes, newlines, tabs, control characters and (optionally) non-ASCII as \uXXXX. Use it to embed text inside a JavaScript or TypeScript string literal.

FAQ
Frequently asked questions
What is the difference between escaping and encoding?
Escaping adds backslashes or entities so special characters are treated as text inside a specific language. Encoding (like Base64 or URL encoding) transforms the whole text into a different representation.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
