Build custom column headers and instantly download thousands of rows of realistic dummy data for database imports and Excel testing.
Enterprise CSV Generation Features
Design exact spreadsheet replicas. Add, name, and reorder columns so your downloaded CSV perfectly matches the headers expected by your database.
Populate your spreadsheets with mathematically unique IDs, formatted Dates, realistic Names, Addresses, E-commerce prices, and complex tracking numbers.
Need to test a massive database import? Generate up to 5,000 unique rows of sample data in a single click without slowing down your browser.
Our compiler strictly handles value escaping. If a generated company name contains a comma, we safely wrap it in quotes so your columns never break in Excel.
Check the "Unique" box on any column (like Emails or UUIDs) and our engine guarantees mathematically that no two rows in your spreadsheet will be identical.
Your table structures are highly sensitive. Because all generation happens locally in your web browser, your custom schemas never touch our servers.
