The Regex Tester tool allows users to enter a regular expression pattern and test it against a block of text. It helps in verifying whether the pattern correctly matches the intended parts of the input.

Regex Tester - Instruction Manual

• Step 2: Type or paste the text you want to test into the text area.
• Step 3: Click the “Test” button.
• Result: The tool will highlight any matches found in the text, or indicate that no match was found.
