Bulk UUID Generator

About this tool

Generate any number of version-4 UUIDs at once. UUIDs are 128-bit identifiers that are practically guaranteed to be unique, ideal for database keys and distributed systems.

Example

Input: count 3

Output: 3 lines like 9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d

How to use this tool

1. Choose how many UUIDs you want to generate.
2. Enter the quantity in the bulk input field.
3. Click generate to create the UUID list.
4. Copy the results and paste them into your app, test data, or database.

Step by step, what happens

1. The tool reads the number of UUIDs you request.
2. It generates version-4 UUIDs using cryptographically random values.
3. Each UUID is formatted in the standard RFC 4122 layout.
4. The tool returns the full list instantly so you can copy it or regenerate if needed.

Worked example

For a test seed file, you might want three unique UUIDs to use as database IDs.

Input: 3

1. You enter 3 as the number of UUIDs to generate.
2. The tool creates three separate version-4 UUIDs.
3. It displays them as a plain list, one UUID per line, ready to copy.

Tips and common mistakes

• Use bulk generation when you need many IDs for seed data or test fixtures.
• UUID v4 values are best when uniqueness matters more than readability.
• Do not treat UUIDs as secret values just because they are hard to guess.
• If you need one ID, you can still use this tool and generate a single UUID.
