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 GUIDs in one click, with 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 supports the pure string form without hyphen.
4. Cross-platform use： Browser-based operation, compatible with Windows, macOS, Linux and other systems, no need to download or install.
