This page opens the string escaper with JavaScript/TypeScript mode preselected — pick single quotes, double quotes or backticks and paste your raw string to get a copy-paste-ready literal.

Each quote style escapes only what it needs: single-quote mode escapes ', double-quote mode escapes ", and backtick mode escapes ` and template-literal ${ sequences — plus backslashes, newlines, tabs and carriage returns in every style.

Decode mode reverses common JS escapes, including \uXXXX and \xXX sequences, back to the original characters. The full tool also handles JSON, SQL and regex escaping, everything running locally in your browser.

Accepted Formats & Rules

  • Live conversion on every keystroke — no button to press.
  • JavaScript mode lets you pick single quotes, double quotes or backticks, and escapes exactly what that quote style needs, including template-literal ${.
  • Clear, localized error messages when a malformed escape sequence can't be decoded, instead of a crash or a blank result.

Key Benefits

✓ Zero server round-trip: every escape and unescape happens instantly in your browser tab.
✓ Four real formats: JSON, JavaScript/TypeScript with a quote-style choice, SQL and regex — not simplified stand-ins.
✓ Honest SQL warning: a clear, persistent disclaimer keeps quick escaping separate from production-safe parameterized queries.

Use Cases

  • • Escape a user bio or search term before splicing it into a hand-built JSON string in a shell script or config generator, so quotes and newlines don't break the payload.
  • • Get a copy-paste-ready JavaScript string literal in your chosen quote style — including the ${ escaping template literals need — instead of hand-escaping backslashes by eye.
  • • Turn a user-typed search phrase into a safe literal for new RegExp(), so periods and asterisks in the query are matched exactly instead of acting as wildcards.
