How to Generate Realistic Test Data for Development and QA
Free, step-by-step guide. No signup needed — everything runs in your browser.
1
Open the Fake Data Generator
Navigate to the tool. No signup, nothing to install.
2
Pick the fields you need
Tap the fields you want — names, emails, addresses, phones, companies, credit cards, UUIDs. Selected fields highlight in blue.
3
Set row count and format
Choose how many rows (1–1000), then output format: Table for preview, JSON for code, CSV for spreadsheets.
4
Generate, copy, or download
Hit Generate. Use Copy for clipboard or Download to save the file. Use the rows directly in your tests or fixtures.
Tips for best results
- Credit card numbers pass the Luhn checksum but are NOT real cards — safe to use in test forms, will fail at real payment gateways.
- Emails look real but use generic test domains so you cannot accidentally email a real person from your test environment.
- For database seeding, the JSON output drops straight into a seed file or migration. The CSV works with most spreadsheet imports.
- Do not use generated fake data in production user-facing copy — it is for testing, mockups, and demos only.
- Need 10,000+ rows? Use the faker library directly in your test setup — generation in the browser is capped at 1000 for UX.
