About the Large CSV Generator

The Large CSV Generator creates realistic sample data for testing imports, demos and spreadsheets: names, emails, phone numbers, companies, addresses and more, as CSV or Excel files.

Everything is generated in your browser; nothing you enter is uploaded, and anything random comes from a cryptographically secure source.

How to use the Large CSV Generator

  1. Choose the fields (columns) you need and their order.
  2. Set the number of rows, up to 1,000.
  3. Click Generate, then download CSV or Excel (.xlsx).

Frequently asked questions

Is the data real?

No. Every record is generated randomly, so it is safe to use in demos and tests without privacy concerns.

Does it slow down my browser?

Generation runs in a background worker, so the page stays responsive.
