Why this one is useful
Batch generation is faster than copying one UUID at a time when you are filling fixtures, imported records, or admin seed data.
Prefixes, suffixes, and separator control let you adapt the output to code, CSV-like data, or quick manual pastes.
Output templates and presets make it much faster to jump into JSON fixtures, SQL inserts, or compact identifier lists.
It runs fully in the browser, so there is no request, no login, and no waiting around for a basic task.
Common uses
Generating record IDs for imports, webhooks, and internal tools.
Preparing test users, orders, and seeded database rows.
Creating compact identifiers for logs and quick prototypes.
Making one-off identifier lists for QA and admin tools.
Prepare IDs for test records
Choose the number of UUID v4 values you need, then pick a format that matches the destination. Plain lines work for spreadsheets; JSON and SQL output save quoting and comma work when seeding records.
A fixture task
For ten sample users, generate ten IDs at once and copy the JSON list into your fixture. Use the standard hyphenated form when a database UUID column expects conventional UUID text.
Check the destination format
Prefixes, suffixes, compact strings, and braces can be useful for labels but may not be accepted by a UUID typed database column. Test an import with one value first.
