Simple GUID Generator

Number of Guids to generate (1-2000):
UPPERCASE {Braces} Hy-ph-ens

What is this and how do I use it?

The above tool can be used to generate as many GUIDs as you'd like, up to a maximum of 2000

As a software developer myself, I find that I frequently need to generate GUIDs quickly and easily and don't always have access to Visual Studio, which would otherwise be how I generate them.

What is a GUID?

Wikipedia describes GUIDs as follows:

A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. The term globally unique identifier (GUID) is also used.

When generated according to the standard methods, UUIDs are for practical purposes unique, without depending for their uniqueness on a central registration authority or coordination between the parties generating them, unlike most other numbering schemes. While the probability that a UUID will be duplicated is not zero, it is so close to zero as to be negligible.

Thus, anyone can create a UUID and use it to identify something with near certainty that the identifier does not duplicate one that has already been, or will be, created to identify something else. Information labeled with UUIDs by independent parties can therefore be later combined into a single database, or transmitted on the same channel, without needing to resolve conflicts between identifiers.

Adoption of UUIDs and GUIDs is widespread, with many computing platforms providing support for generating them, and for parsing their textual representation.
