JSON String Escaper

Escape text into a JSON string

Putting arbitrary text inside a JSON string requires escaping certain characters: double quotes and backslashes must be prefixed with a backslash, and control characters such as newlines and tabs become their escape sequences. This tool does it reliably using the same rules as a standards-compliant JSON encoder. Paste any text and it produces a valid JSON string literal, complete with surrounding quotes, ready to embed in a JSON document or source code. It also works in reverse, unescaping a JSON string back to the original plain text.

This removes the guesswork and the subtle errors that come from escaping strings by hand.

When to escape JSON strings

Developers constantly need to embed snippets of text, HTML, SQL or other JSON inside a JSON value, whether writing fixtures, crafting API request bodies, or building configuration. Any stray quote or newline would otherwise break the JSON, so correct escaping is essential. Unescaping is equally handy for reading a value pulled from a JSON payload or log.

Because the tool uses the browser's native JSON encoder and decoder, the output is guaranteed to be valid and matches what every conforming JSON parser expects. All processing happens locally in your browser, so your text stays private.
