generate multiple uuids at once
Database seeds, test fixtures and migration scripts often require dozens or hundreds of pre-generated UUIDs. This page explains how to get the batch and use it safely in different contexts.
Copy directly from the batch text field.
Use the result as technical or educational support, keeping the tool limits explicit in the workflow.
A UUID v4 is a 128-bit unique identifier generated with random bits, except for the 4 version bits (position 13) and 2 variant bits (position 19). The format is xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where y is 8, 9, a or b.
For seeds and static reference data, yes. For runtime-generated IDs (new users, orders, etc.), generate them in application code — never reuse pre-generated lists in production, as that does not guarantee uniqueness across instances.
No. It helps explain the scenario and use the tool more safely, but real decisions should consider official sources, full context and qualified guidance when needed.
