    What is a Bulk UUID Generator

    The bulk generator is the same v4 engine as the single-uuid tool, wrapped for volume. You choose how many values to create (up to 1000 in one pass) and download them all at once.

    Values are generated locally with the Web Crypto API and never sent anywhere, so even large batches stay private.

    How to

    1. Enter the count (1–1000) in the field or tap a quick preset (1, 5, 10, 50, 100).
    2. Press Generate. The list updates instantly.
    3. Use Copy all or Download .txt / .csv to capture the full batch.

    Use cases

    • Seeding databases and lookup tables with unique rows.
    • Test and demo fixtures that need many distinct IDs.
    • Batch imports where each record requires its own identifier.

    Code examples

    Python

    import uuid
    ids = [str(uuid.uuid4()) for _ in range(1000)]
    open('ids.txt','w').write('\n'.join(ids))

    SQL

    INSERT INTO t(id) VALUES
      ('<uuid>'),('<uuid>'),('<uuid>');  -- generate per row

    Frequently asked questions

    How many UUIDs can I generate at once?

    Up to 1000 per batch. For more, run the generator again or loop in your own script.

    What format is the CSV?

    Two columns: index,id — the row number and the UUID — so you can join it to other data easily.

    Are bulk UUIDs unique?

    Yes, each is an independent v4 value; the chance of a duplicate in 1000 is astronomically small.
