Test Data Generator (German)

Generate realistic German test data - names, addresses, IBAN and more

Fields

What is the Test Data Generator?

The Test Data Generator creates realistic but fictitious German personal data for development and testing purposes. The generated data includes first names, last names, email addresses, street addresses with house numbers, postal codes, cities, federal states, phone numbers, IBAN numbers, and birth dates. All data is based on realistic German data pools and is perfectly suited for unit tests, database seeds, and prototypes. The postal codes are mapped to real German cities, and street names come from a pool of typical German designations.

How do I use the Test Data Generator?

Use the checkboxes to select which fields your test data should contain. Set the desired count (1 to 100 records) and choose the output format: JSON for APIs, CSV for spreadsheets, or SQL INSERT for direct database import. Click "Generate" and copy or download the result.

Why generate test data online?

For software testing and development, you regularly need realistic data. Using real personal data is problematic for data protection reasons (GDPR). Our generator creates all data directly in your browser - nothing is sent to a server. The data is realistic enough for meaningful tests but completely fictitious. No account needed, no installation, ready to use immediately. This makes it the perfect solution for GDPR-compliant test data generation.

Frequently Asked Questions

Is the generated data real?
No, all data is fictitious. Names, addresses and IBANs are randomly assembled and do not refer to real people.
Are the IBANs technically valid?
Yes, the IBANs follow the correct format and pass checksum validation, but the bank accounts behind them do not exist.
Is the data GDPR-compliant?
Yes, since no real personal data is used or stored, the generator is well suited for GDPR-compliant testing scenarios.
Which output formats are supported?
You can export the data as JSON, CSV or SQL INSERT statements.
