Is any data sent to a server?

No. All CSV data is generated entirely in your browser using JavaScript. Nothing is uploaded or stored remotely.

What are the preset schemas?

Users includes id, name, email, age, and city. Products includes id, name, price, category, and stock. Orders includes order_id, customer_id, date, amount, and status.

Can I add my own columns?

Yes. Select the Custom schema and type in as many column names as you need. Each custom column is filled with realistic mixed data.

Are the email addresses real?

No. All generated values are fictional and safe for testing. Emails follow a realistic pattern but are randomly constructed from built-in name lists.

How many rows can I generate?

Up to 1,000 rows per download. For larger datasets, generate and download in batches.

What encoding does the CSV use?

UTF-8. Fields containing commas or quotes are properly quoted per the RFC 4180 CSV standard.
