Bulk-generating random UUIDs
Sometimes you need more than one ID — seeding a test database, pre-generating identifiers for a batch import, or filling in sample data for a demo. This tool generates a list of random (version 4) UUIDs in one go, with options to format them uppercase or strip the hyphens to match whatever system you're feeding them into.
Frequently asked questions
- What's the maximum number I can generate at once?
- 100 per click. Click generate again to get a fresh batch.
- Can I paste these straight into a SQL insert or a CSV?
- Yes — use "Copy all" to grab the full list (one UUID per line), then paste it into your spreadsheet or script and adjust formatting as needed.
- Are they cryptographically random?
- Yes, they're generated using the browser's crypto.randomUUID() API, which relies on a cryptographically secure random number generator.
