Frequently Asked Questions
How do I generate a sample CSV file?
Add the columns you need, choose a data type for each (like full name, email, or date), set the row count, and click Generate. The file is created instantly in your browser and you can download it or copy it.
What data types can I generate?
Full names, first and last names, email addresses, phone numbers, street addresses, cities, countries, company names, dates, integers and decimals in a range you set, booleans, UUIDs, and sequential IDs.
Is the generated data real?
No — every value is randomly generated fake data. Names, emails, and addresses are synthesized from sample word lists, so the output contains no real personal information and is safe to share.
How many rows can I generate?
Up to 100,000 rows per file. Generation happens locally, so speed depends on your device rather than an upload limit.
Is the CSV Generator free to use?
Yes, completely free with no limits. No signup or download required.
