Why Use This Tool?

Regular expressions can be tricky to get right. They are powerful, but their complexity can lead to errors if not tested thoroughly. Our Advanced Regex Validator simplifies this process by providing a clear, intuitive interface for testing and refining your regex patterns. This tool saves time, reduces errors, and enhances your productivity by providing instant feedback on your regex patterns.

Features

• Pattern Matching: Test your regex patterns against any text string.
• Modifiers: Use global, case-insensitive, and multiline modifiers to refine your searches.
• Highlight Matches: See highlighted matches directly in the test string.
• Detailed Match Information: Get detailed information about each match, including its position in the string.
• Dark Mode: Switch to dark mode for a comfortable viewing experience in low-light environments.
• Data Privacy: Your data won't be stored by us. All processing happens locally in your browser.

Step-by-Step User Guide

1. Enter Regex Pattern: In the "Regex Pattern" input field, enter the regex pattern you wish to test. For example, to match all words starting with a capital letter, you might use the pattern ([A-Z])\w+.
2. Select Modifiers: Use the toggle switches to select any necessary modifiers:
   • Global (g): Find all matches, not just the first one.
   • Case Insensitive (i): Match letters regardless of case (e.g., a matches both a and A).
   • Multiline (m): Make ^ and $ match the start and end of each line, not just the start and end of the whole string.
3. Enter Test String: In the "Test String" textarea, input the text you want to test your regex pattern against. For example, "Once upon A time There was a King with Seven sons".
4. Click "Match": Press the "Match" button to validate the pattern. The tool will process the pattern and test string based on the selected modifiers.
5. Review Results: The results will be displayed in the "Result" section:
   • Match Success: If the pattern matches, the matched text will be highlighted in yellow, and detailed information about each match will be provided.
   • Match Failure: If the pattern does not match, a message will indicate that no matches were found.
6. Toggle Dark Mode: Use the dark mode toggle switch to switch between light and dark themes for a more comfortable viewing experience.
