How to use
- Choose “Fake records”, set the number of rows and an output format (JSON, JSONL, CSV or SQL).
- Edit the field list: rename keys and pick a type for each. Add or remove fields as needed.
- The same seed always produces the same data, so tests stay reproducible. Click “New seed” for a different batch.
- Switch to “Placeholder text” for Lorem ipsum or Chinese filler paragraphs.
FAQ
Is the data real?
No. Names and addresses are combined from fictional lists, emails use example domains reserved for documentation, and US phone numbers use the 555-01xx range reserved for fiction. Chinese mobile numbers are random and may coincide with real ones, so never use them to send messages.
Why use a seed?
A fixed seed makes the output deterministic: snapshot tests and demos get the same data every time, while changing the seed gives a fresh set.
