Regular Expression Escape Tool is a free online utility designed to help developers and users work with regular expressions more efficiently. This tool allows you to easily escape special characters in text to make them safe for use in regular expressions, as well as unescape previously escaped regex patterns. Special characters in regular expressions like [ ] \ ^ $ . | ? * + ( ) { } need to be escaped with a backslash when used as literal characters in a pattern. Our tool automates this process, saving you time and preventing common regex syntax errors. Whether you need to escape user input for regex matching, or decode a regex pattern to understand its structure, this tool provides a simple and intuitive interface for both operations.
