Regex to English Explainer

Regular Expressions are one of the most powerful tools in programming—yet also one of the most confusing. A single regex pattern can look like unreadable symbols, making it difficult to understand what it actually matches or why it behaves a certain way. Developers often copy regex patterns from online sources without fully understanding them, which can lead to bugs, security issues, or inefficient code. That’s where the Regex to English Explainer (Visual) becomes invaluable. This intuitive Regex Explainer translates complex regular expressions into clear, plain-English explanations so you can understand, debug, and learn regex with confidence.
