Bulk UUID v4 / v7 generator

Generate 1–1000 UUID v4 or v7 values and choose canonical, uppercase, compact, or URN output.

Input & settings

Lock version and formatting before a batch

For test data, choosing v4/v7 and the text format up front avoids mixed identifiers that are harder to compare later.
