Bulk UUID Generator: Create Multiple GUID Values
The bulk UUID generator prepares a list of identifiers for fixtures, test tables and demo data. Use a UUID version that your application supports.
Bulk generation does not enforce database uniqueness or provide authentication security. Critical systems still need unique constraints and suitable access controls.
How to use it
- Choose how many values you need.
- Select a supported UUID version and generate the list.
- Check the format and move the output into your test data.
Example
Input: Generate five UUID v4 values
Output: A five-line UUID list in the expected format.
Who is it for?
- Test developers
- Teams creating demo data
- Developers learning UUID formats
Privacy and limitations
The list is generated in this browser and is not sent to an API for storage.
UUID and GUID: How Unique Identifiers Work
Frequently asked questions
Should I choose UUID v4 or v7?
Consider ordering, time information, compatibility and privacy requirements in your system. Use only versions your application supports.
How many values can I create?
The interface limit can affect browser responsiveness. Avoid generating more rows than you need.
Can a list contain duplicates?
A collision is extremely unlikely but not theoretically impossible. Enforce uniqueness in production storage.
Are generated identifiers saved?
The tool creates the list in this browser and does not store it on a Yula server.
