Technical reference

Generate fake data locally in your browser for testing and development. Supports Chinese and English names, emails, and addresses. Output as JSON, CSV, or SQL with fixed seeds for reproducibility.

Core features

  • Generates fake data records with names, emails, phone numbers, addresses, and more.
  • Supports both Chinese (zh-CN) and English (en) data locales.
  • Output as JSON, CSV, or SQL format.
  • Fixed seed support: same seed and config always produce identical data for reproducibility.
  • Generate 1-500 records with one-click random seed regeneration.

Example: generated JSON

In fixed seed mode, the same seed and configuration always generate identical data, ideal for deterministic test cases. Random seed mode produces different data each time.

  • Maximum 500 records; excess is truncated.
  • Generated emails and phone numbers are fictional and do not correspond to real individuals.

Frequently asked questions

What is a seed?

A seed is the initial value for the pseudo-random number generator. The same seed with the same config always produces identical data, useful for reproducing test results. Click the random seed button for new non-reproducible data.

Is the generated data real?

No. All data is fictional. Names, emails, and phone numbers do not correspond to any real person. For development and testing purposes only.
