What GUID & UUID Generator helps you do

Use this GUID generator when you need one UUID fast or a batch of identifiers for test data, seed scripts, copied examples, or API work.

You can switch between common output formats and generate multiple values at once instead of creating them manually in code.

Use the standard .NET GUID formats: N no separators, D hyphenated, B braces, P parentheses, and X hexadecimal structure.

GUID format examples

The underlying value stays the same while the string representation changes. For example, the same GUID may appear hyphenated in format D, compressed in format N, or wrapped in braces or parentheses in formats B and P.

Frequently asked questions

What is a GUID used for?

GUIDs and UUIDs are commonly used as unique identifiers in databases, APIs, distributed systems, event tracking, and test fixtures.

What is the difference between GUID and UUID?

In most practical development use, people use the terms interchangeably for the same kind of 128-bit unique identifier.

Can I generate multiple UUIDs at once?

Yes. This tool supports batch generation so you can copy several IDs in one run.

What is the difference between D, N, B, P, and X formats?

Those formats change how the same GUID is displayed, such as whether it uses hyphens, braces, or parentheses.
