Regex escape

Client

Escape dots, parentheses, and other metacharacters before embedding text in a regex pattern.

When to escape regex literals

Metacharacters like . * + ? ( ) [ ] { } | \ ^ $ must be backslash-escaped before you embed user text inside a JavaScript RegExp. Paste the literal, copy the escaped output, then paste into your pattern on Regex tester.

Common use cases

  • Build a literal match for user-supplied search terms in JavaScript.
  • Prepare safe fragments before combining into larger regex patterns.
  • Debug why a hand-written pattern fails on punctuation-heavy input.

Common mistakes to avoid

  • Double-escaping

    Run escape once on the raw literal—do not escape an already escaped string.

  • Expecting full regex syntax

    Output is a literal fragment; wrap with ^ $ or flags in your own pattern.
