What is the Text Pattern Tester?

The Text Pattern Tester (formally known as a Regular Expression or 'Regex' Tester) helps you build smart search rules. Instead of just searching for an exact word, you can search for a pattern—like 'find any text that looks like a phone number or an email address.' This tool lets you test those rules before you use them.

How to use it

  1. Type your 'Regex' pattern in the top input box.
  2. Paste some sample text into the large text area below.
  3. The tool will instantly highlight any text that matches your pattern.
  4. Adjust your pattern until it highlights exactly what you expect.

Common Use Cases

  • >Verifying that your code will correctly catch invalid email addresses.
  • >Extracting phone numbers from a massive block of disorganized text.
  • >Cleaning up and formatting messy spreadsheet data automatically.
