GUID online generation tool

GUID（Globally Unique Identifier,全局唯一标识符）是由16字节（128位）二进制数组成的唯一ID,格式为“xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx”. It has a very low probability of duplication and is widely used in software development, database primary keys, distributed systems and other scenarios.

Tool Functions

1. Quick Generation： Generate RFC 4122 compliant GUID with one click, support case-sensitive switching.
2. Batch Generation： Generate multiple GUIDs at once to meet batch requirements.
3. Format compatibility： The generated result contains standard hyphenation format (e.g.550e8400-e29b-41d4-a716-446655440000）， and support the pure string form without hyphen.
