About This Calculator
This batch generator produces up to 1,000 unique random (v4) UUIDs in a single run, separated by newlines or commas.
Each UUID uses the browser’s cryptographically secure random generator, so duplicates are practically impossible even across thousands of outputs. Copy the whole batch straight into a spreadsheet, file, or migration script.
Generation happens entirely in your browser.

Frequently Asked Questions
Is there any risk of duplicates in a large batch?
Essentially none. v4 UUIDs have 122 random bits, so the chance of two colliding even among 1,000 is negligible.
Can I generate more than 1,000?
The cap is 1,000 per run to keep the output manageable. Run it multiple times and concatenate if you need more.
