Code Examples
JavaScript
const ids = Array.from({ length: 250 }, () => crypto.randomUUID());Python
import uuid
ids = [str(uuid.uuid4()) for _ in range(250)]Frequently Asked Questions
How long does 250 take?
A few milliseconds. The generator pulls 64 KiB of entropy at a time, so large batches stay fast.
Can I get them as SQL?
Not directly — download .csv and wrap the column in your own INSERT statement.
