Result

This page opens the string escaper with SQL mode preselected — paste a string like a name or a search term and see it escaped for a SQL string literal as you type.

SQL escaping here doubles single quotes (O'Brien becomes O''Brien), the classic ANSI SQL rule for embedding a literal quote inside a quoted string.

Important: this is for understanding SQL escaping and quick one-off scripts only — it is not a substitute for parameterized queries or prepared statements in real applications, and the page keeps that warning visible. The full tool also escapes JSON, JavaScript and regex strings, all 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.
