Text Uuid Generator

Updated 2026-09-13 · DocsAll Guides

Quick answer: Generate v4 UUIDs in bulk for IDs, test fixtures, and tracing. Open 文本UUID 生成 — everything runs locally in your browser, and files never leave your device.

Steps

  1. Open the UUID generator.
  2. Set the count and generate.
  3. Copy the list.

Important notes

  • v4 UUIDs are random — fine for order IDs and trace IDs, wrong for security tokens (use cryptographic secrets).
  • As primary keys, random UUIDs hurt index locality at scale; consider auto-increment or ULID.

Common questions

Can they collide? Astronomically unlikely — about one in a billion per billion generated.

v7? v4 only here; for time-ordered IDs use ULID.

When to use this

For test fixtures, generate a fresh set per run instead of reusing literals — duplicated IDs mask real bugs in joins and dedupe logic.
