Bulk UUID v4 Generator

Bulk UUID v4 generation is essential for developers seeding databases, creating test fixtures, or provisioning resources at scale. This generator produces up to 100 randomly generated version 4 UUIDs in a single click. You can choose uppercase formatting or wrap each UUID in curly or square braces to match your exact schema or framework requirements. UUIDs generated here are statistically unique and safe for use as primary keys, correlation IDs, or distributed system tokens without any central coordination.

Use Cases

  • •Bulk database seeding
  • •Test fixture generation
  • •Batch API request IDs
  • •Distributed system tokens
  • •Mock data creation

FAQ

What is the difference between UUID v4 and other UUID versions?

UUID v4 is randomly generated with no dependency on time or hardware, making it the most commonly used version for general-purpose unique identifiers.

Can I generate 100 UUIDs at once?

Yes — this generator supports up to 100 UUIDs per click, all formatted to your chosen style.

Why would I wrap a UUID in curly braces?

Some systems like Microsoft SQL Server and certain ORMs expect GUIDs wrapped in curly braces by convention.

Are these UUIDs safe to use in production?

They are statistically unique and suitable for most use cases, but for cryptographic purposes consider a server-side implementation.
