What is the Dummy Data Generator?

A dummy data generator creates realistic-looking fake records for testing, demos and mockups. Pick the fields you need, choose a locale, and generate users as JSON, CSV or SQL INSERT statements without inventing a single record by hand.

Developers and QA teams constantly need sample data, and generating it in the browser keeps test data off any server. For large requests, a Web Worker produces up to 100,000 rows without freezing the page.

How to use the Dummy Data Generator?

  1. Choose the number of rows (up to 100,000) and a locale.
  2. Select the fields you want and the output format.
  3. Click Generate, preview the result and download the file.
