Generate random v4 or time-ordered v7 UUIDs and ULIDs in bulk, and decode the creation time hidden in a v7 UUID or ULID.
Create one ID or ten thousand, as plain lines, JSON, SQL or CSV. Version 7 UUIDs and ULIDs start with a timestamp, which keeps database indexes compact – and the decoder reads that time back out, so you can tell when a record's ID was created.
ULIDs convert to UUID notation and back, for databases that only have a UUID column.
