How to Use UUID Generator

What is UUID Generator?

A UUID (Universally Unique Identifier) is a 128-bit identifier designed to be globally unique without requiring a central authority. This tool supports v1 (time-based), v4 (random), and v7 (time-ordered, RFC 9562) UUIDs. They are widely used as primary keys in databases, session tokens, and distributed system identifiers.
