Extract Regex Matches

Enter a regular expression pattern and extract every matching piece of text from your input — great for finding specific patterns in large amounts of text.

What Does This Tool Do?

Regular expressions (regex) are powerful patterns for finding specific types of text. This tool takes your regex pattern and finds every occurrence in your text, giving you a clean list of all matches. For example, extract all phone numbers, all dates in a specific format, or any custom pattern you define.

How It Works

Your regex pattern is compiled into a JavaScript RegExp object with the flags you selected (g for global, i for case-insensitive, m for multiline). The pattern is then applied to your text using matchAll() and all matches are collected into the output list.
