About This Batch
- This page is the batch generator preset to 500. Batches this size are almost always consumed by a script or an import, so the download is the primary output.
How to generate
- Pick a version and any formatting (uppercase, hyphens, braces).
- Leave how many at 500 — or change it, up to 10,000.
- Press Generate, then Copy all or Download.
Use Cases
- Import files for a bulk data migration.
- A volume of records large enough to expose indexing behaviour.
- Bulk test payloads for a queue consumer.
Code Examples
JavaScript
const ids = Array.from({ length: 500 }, () => crypto.randomUUID());Python
import uuid
ids = [str(uuid.uuid4()) for _ in range(500)]Frequently Asked Questions
Is the copy button reliable for 500 values?
Yes, though for batches this size the .txt or .csv download is usually easier to move around.
