What characters get escaped?

Double quotes, backslashes, tabs, newlines, carriage returns and other control characters are escaped, and the result is wrapped in double quotes so it is a valid JSON string literal.

What is the difference between this and JSON Escape / Unescape?

This tool returns a complete JSON string literal — including the surrounding double quotes — ready to paste as a value. The JSON Escape tool returns only the escaped body without the outer quotes. Pick whichever matches where you are pasting.

Does unescape need the surrounding quotes?

No. You can paste the literal with or without the outer double quotes — the tool adds them if they are missing before decoding.

How is a multi-line block of text handled?

Each line break is converted to a \\n escape, so the whole block becomes one quoted string. Unescaping turns the \\n escapes back into real line breaks.

Is the output spec-correct?

Yes. Escaping uses the browser's native JSON.stringify and unescaping uses JSON.parse, so the result follows the JSON specification, including \\uXXXX unicode escapes for control and non-ASCII characters.

What happens if I unescape invalid input?

Unescaping runs JSON.parse, so a malformed literal — an unterminated string or a bad escape sequence — is reported as an error rather than producing a wrong result.

Is my text uploaded anywhere?

No. Escaping and unescaping run entirely in your browser with JavaScript, so your text never leaves your device.

JSON String Escape / Unescape

Escape and unescape JSON strings in your browser

To embed arbitrary text as a value in a JSON document, it has to become a valid JSON string literal — quoted, with every special character escaped. This tool turns raw text into that literal and decodes a literal back to plain text, so you can safely paste multi-line content into a JSON config, log line or API payload.

How it works

Escaping runs your text through the browser’s native JSON.stringify, which escapes the special characters and wraps the whole value in double quotes. Unescaping runs JSON.parse (adding the outer quotes first if you left them off), turning the escapes back into the original characters.

Character	Becomes
`"`	`\"`
`\`	`\\`
newline	`\n`
tab	`\t`
carriage return	`\r`
control / non-ASCII	`\uXXXX`

The result is a complete literal including the surrounding quotes — unlike the companion JSON Escape tool, which returns only the body.

Example

Escaping this two-line text:

Path: C:\temp
Done

produces the literal:

"Path: C:\\temp\nDone"

Unescaping that literal restores the original two lines exactly. Everything runs locally in your browser — nothing is uploaded, which makes it safe for confidential text and snippets.
