Escaped result

  

About this tool

Searching for price is $9.99 (each) with a regex fails hilariously unless every special character is escaped. This tool escapes all regex metacharacters.*+?^${}()|[]\ — and can wrap the result as a ready literal for JavaScript, PHP (preg_quote) or Python (re.escape).

The unescape mode reverses it when you need the original text back.

How to use it

  1. Paste the text you want to match literally.
  2. Pick a target: plain pattern, JavaScript, PHP or Python.
  3. Optionally escape forward slashes for /.../ literals.
  4. Copy the escaped result or generated code snippet.

Useful ways to apply it

  • Building a regex from user input safely.
  • Searching logs for strings full of dots and brackets.
  • Writing find-and-replace patterns in editors.
  • Generating language-correct escaping without memorizing rules.

Frequently asked questions

Which characters are escaped?
The regex metacharacters . * + ? ^ $ { } ( ) | [ ] and backslash — plus / optionally, for regex literals delimited by slashes.
What do the language modes add?
They wrap the escaped text in correct string/regex syntax for that language and show the built-in equivalent (RegExp, preg_quote, re.escape) so you can use either.
Does escaping change matching behavior?
Escaped text matches itself exactly — nothing more. That's the point: any special meaning is neutralized.
