Regular expressions, also known as regex or regexp, are a sequence of characters that define a search pattern. They can be used to search, edit, or manipulate text. Regular expressions are used in a variety of programming languages and text editors, and they are an essential tool for many developers and writers.

A regex tester is a tool that can be used to test and validate regular expressions. Regex testers can be used to:

• Test regular expressions against a given input string to see if they match.
• Debug regular expressions by identifying errors in the syntax or structure of the regular expression.
• Learn about regular expressions by providing a visual representation of how regular expressions work.

To use a regex tester, simply enter the regular expression that you want to test into the input field and enter the input string that you want to match the regular expression against into the input string field. The regex tester will then display the results of the test in the output field.

Regex testers can be a valuable tool for anyone who works with regular expressions. Regex testers can help you to test and validate regular expressions, debug regular expressions, and learn about regular expressions.
