How to use Bulk UUID Generator

Get the best out of Bulk UUID Generator: every option explained, a worked example, and what to check when the output is not what you expected.

Updated July 31, 2026

What it does

Generate thousands of Universally Unique Identifiers (UUIDs) instantly in your browser. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

Option	Type	Default	What it does
`count`	whole number	`10`	How many UUIDs to generate (capped at 10000). Accepts min 1. Defaults to `10`.
`version`	one of: v1, v4	`v4`	Defaults to `v4`.

Worked example

Run these settings on the tool page:

count: 10
version: v4

You get:

Getting the result you want

Most of the control here is in the options above. If the output is not what you expected, the setting to check first is count and version — those change the shape of the output rather than the input it accepts.

Troubleshooting

A value is rejected. count accepts min 1. Anything outside that is refused rather than silently clamped.
It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.


Bash
curl "https://api.toolsxpo.com/v1/uuid-bulk-generator" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 2 credits per successful call. See the full endpoint reference, or try it in the playground.
