About the Regex Tester
Regular expressions (RegEx) are powerful search patterns used for string matching and manipulation. This tool allows developers seamlessly test and visualize complex regular expressions dynamically within the browser without sending source data to a server.
How to Use This Tool
- Enter Pattern: Type your regex pattern into the top input (without the surrounding slashes).
- Toggle Flags: Use the standard checkboxes to add common modifiers like Global (g), Case-Insensitive (i), and Multiline (m).
- Enter Test Text: Paste your sample text into the large box.
- Review Matches: The matching captures and sub-groups will automatically render alongside your input text.
