What is Regex?

Regular Expressions (Regex) are patterns used to match character combinations in strings. They are essential for input validation (email, phone numbers), data scraping, and complex text manipulation in software development.

How to Use

1. Regex: Enter your pattern (e.g., [a-zA-Z]+).
2. Flags: Set search modifiers (e.g., g for global search, i for case-insensitive).
3. Test Text: Enter the source text you want to test against.
4. Calculate: View all matched instances and the total match count instantly.

Examples

| Scenario | Regex | Description | | :--- | :--- | :--- | | Email | ^[^\s@]+@[^\s@]+\.[^\s@]+$ | Simple email validation | | Numbers | \d+ | Find all numeric groups | | Title Case | \b[A-Z]\w+ | Find words starting with a capital letter |
