UUID v7 embeds a Unix millisecond timestamp, making generated UUIDs sortable by creation time — ideal for database indexes.
UUID & Test Data Generator is a free online tool for creating UUIDs (v4 random or v7 time-ordered) and dummy INSERT statements for seeding test tables. Define columns in a simple name:type format and generate realistic fake rows — names, emails, dates, numbers — without touching production data.
Yes. The UUID & Test Data Generator is completely free with no signup and no usage limits, like all SqlInt mini tools.
Use v4 for cryptographically random IDs and v7 when IDs should be time-ordered and sortable by creation time.
