Write just the field kinds (name:name) and it fills in believable rows — as many as you want. The same seed always gives the same data.
How to use it
- Write one field per line (e.g. name:name · email:email · joined:date)
- Choose how many rows and which seed
- Take the result as JSON, CSV or SQL
- Put the same seed back in and you get the same data
Common questions
- Why a seed?
- A test that changes every run locks nothing down. So instead of Math.random the rows come from the seed — the same seed always gives the same data.
- Can it produce Korean names?
- Yes. Names and addresses are split per locale (ko/en/ja) — testing a Korean layout with English names gets the character widths wrong.
- Is the generated data uploaded anywhere?
- No. It is generated in your browser and downloaded from there.
