Need to drop a string with quotes, backslashes or line breaks into a JSON payload, a JavaScript source file, a SQL query or a regular expression pattern? Each of those four contexts escapes special characters differently, and getting it wrong breaks the value or introduces a bug. This tool escapes and unescapes text for all four, live, right in your browser. Need HTML entity or URL encoding instead? Use our HTML & URL Encoder / Decoder — this tool deliberately leaves those two formats to it.

Pick a format and the rules switch instantly: JSON mode uses the exact escaping the JSON spec requires (quotes, backslashes, newlines, tabs and control characters); JavaScript mode adds a quote-style choice, so you get single-quote, double-quote or backtick-correct output, including template-literal ${ escaping; SQL mode doubles single quotes the way standard SQL string literals expect; and regex mode escapes the twelve special regex metacharacters so the exact literal text matches inside a new RegExp() pattern — regex escaping only goes one way, since there is no ambiguity to reverse.

One honest caveat: SQL string-doubling is shown here for learning and for quick one-off scripts, never as a substitute for parameterized queries or prepared statements — string-escaping user input by hand is a classic SQL-injection risk in real applications, and the tool says so plainly whenever SQL mode is active. Every conversion runs locally: nothing you paste, encode or decode is ever uploaded.

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.
