About the Regex Tester
Regular expressions (regex) are sequences of characters that specify a search pattern in text. They are an incredibly powerful tool for developers, data scientists, and anyone working with text data. This tool provides an interactive environment to test and debug your regex patterns. As you type your expression and test string, the results update in real-time, highlighting all matches within the text. It also provides a detailed breakdown of each match, including its index and any captured groups, helping you refine your patterns with confidence.
