UUID Tool
Bulk UUID Generator
Need a batch of identifiers for test data, fixtures, or a migration? Produce up to 10,000 UUIDs at once, export them, and keep every value on your own device.
1–10,000 per clickAny version (v1/v3/v4/v5/v6/v7/v8)Export .txt / .csv
Generated locally with the Web Crypto API — nothing leaves your browser.
What Is Bulk UUID Generator?
- The bulk generator is the same engine as the single-UUID tool, wrapped so you can request a large count and work with the result as a list.
- Values are produced on your device with the Web Crypto API. The full list — not just the first rows — is always available for copy and download.
How to generate
- Choose a version and any formatting (uppercase, hyphens, braces).
- Enter how many you need (1–10,000).
- Press Generate, then Copy all or Download as .txt or .csv.
Use Cases
- Test and seed data for databases and fixtures.
- Bulk imports where every row needs a fresh identifier.
- Migrations that assign stable new keys to existing records.
How Bulk UUID Generator Compares
| Bulk tool | One click, thousands of values, list export |
| Single tool | A few values, focus on one identifier |
| API / library | Programmatic generation inside your own code |
Code Examples
JavaScript
const ids = Array.from({length: 1000}, () => crypto.randomUUID());Python
import uuid
ids = [str(uuid.uuid4()) for _ in range(1000)]Frequently Asked Questions
What is the maximum I can generate?
10,000 per click. The interface shows the first 500 for readability, but copy and download always include the complete batch.
Is the full list exported?
Yes. Copy all and the .txt / .csv downloads contain every UUID you generated, not just the previewed rows.
Are bulk UUIDs random enough?
They use the same CSPRNG as the single tool, so the collision math is unchanged — see the collision guide.
