Regex Editor & Tester

This regular expression matches standard UUID (Universally Unique Identifier) formats structured as 8-4-4-4-12 alphanumeric characters separated by hyphens. Although intended for UUID v4, it uses the \w shorthand, meaning it matches any word character sequence in this specific length pattern rather than strictly enforcing hexadecimal digits or version-specific characters. It is highly useful for quickly extracting loosely-formatted UUIDs from larger blocks of text, URLs, or log files.
