Regex Tester & Validator

Matches GUIDs (Globally Unique Identifiers) enclosed in curly braces following the standard format {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}. The pattern uses hexadecimal character classes and an atomic group to prevent backtracking, making it efficient for extracting GUIDs from log files, databases, or configuration files. Works with global and multiline flags to find all occurrences across multiple lines.
