String Escaper & Unescaper

Escape strings for JSON, JavaScript, CSV, SQL, XML or shell — and unescape them again.

To escape a string, paste it above and choose the target format. The tool handles JSON and JavaScript string literals, CSV fields, SQL single-quoted values, XML and HTML entities, POSIX shell quoting and regular-expression metacharacters, and can unescape JSON back to plain text.

Frequently asked questions

Why does escaping differ between languages?

Because each defines its own set of characters that need protecting. JSON escapes quotes, backslashes and control characters; SQL doubles single quotes; a shell needs to protect spaces, dollars and backticks. Applying the wrong one leaves an injection open.

Is escaping enough to prevent injection?

It is the last resort, not the first. Parameterised queries in SQL and proper templating in HTML remove the problem structurally. Manual escaping is correct only where no parameterised interface exists.
