Generate GUIDs online for free. Create unique GUIDs instantly, format them for developers, copy results, and export GUIDs for applications, databases and testing.
Check a GUID and inspect its version, variant and normalized format.
A GUID, or Globally Unique Identifier, is a 128-bit identifier used to uniquely identify records, users, objects, transactions, API resources and other data in software applications.
GUIDs are widely used in databases, Microsoft .NET applications, APIs, distributed systems, microservices, testing environments and software development.
This GUID Generator lets you create GUIDs directly in your browser. Generate one GUID or thousands of GUIDs, change the output format, search generated results and export them for development and testing.
GUID v4uses randomly generated values and is suitable for general-purpose identifiers. GUID v7contains a Unix millisecond timestamp and is designed for identifiers where time ordering can be useful.
The standard GUID format contains 32 hexadecimal characters separated by hyphens. You can also generate uppercase GUIDs, remove hyphens, add braces or parentheses, or use the UUID URN representation.
Developers can use this tool to generate test identifiers for databases, APIs, applications, Microsoft .NET projects, microservices, software testing and development environments.
The SQL output option creates INSERT statements using your selected table and column names. This can be useful when preparing test records or sample database data.
GUID and UUID generally refer to the same 128-bit identifier concept. GUID is commonly associated with Microsoft and Windows development, while UUID is the broader term used across software systems.

Choose the number of GUIDs you need, select an output format if required, and click Generate GUIDs. The GUIDs are generated directly in your browser.
Version 4 GUIDs use randomly generated values and have an extremely large identifier space, making accidental collisions extremely unlikely when generated correctly.
Yes. You can generate multiple GUIDs in one operation and copy or download the generated results.
Yes. GUIDs are commonly used as identifiers for database records, APIs, applications, test data and distributed systems.
Yes. The GUID Generator provides developer-friendly output options including plain text, JSON, CSV and SQL formats.
No. GUID generation is performed in your browser using the Web Crypto API when available. The generated GUID values are not intentionally uploaded to our server.
