# Regex Scanner
**Purpose:** The Regex Scanner is designed to search for and extract text patterns that match specific regular expressions (regex) within text data.
**Functionality:** It applies user-defined or predefined regex patterns to text inputs to identify and extract information that conforms to those patterns.
**Implementation:** The scanner processes text inputs using efficient pattern matching algorithms to locate substrings that match the specified regex patterns. It supports a wide range of regex syntax and features for flexible pattern matching.
**Usage:** Regex Scanner is commonly used in text processing tasks such as data extraction, text validation, and text transformation, where precise pattern matching is required.
To create a regex for a custom string, try this intuitive regex builder:
{% embed url="" %}
{% endembed %}
