Notes

You name the fields yourself, so the JSON keys match your model and the SQL columns match your table. Start a sequence at 1000, cap a price, give an enum the four statuses your state machine has, and the output can go into a seed script as it is.

The language setting changes the data too. Turkish names come with Turkish addresses, and German postcodes have five digits. I use it to check how an app copes with names that have diacritics.

Questions

What can I export?
JSON, CSV, NDJSON or SQL. The SQL is a CREATE TABLE inferred from the generated values, followed by one multi-row INSERT. Every format is rendered on the server, so what you copy matches what was generated.
Is the data safe to put in a demo?
Yes. Everything is generated, nothing comes from real records, so there's no personal data in it and nothing to anonymise.
How many rows can I generate at once?
Up to 500, with up to 25 fields. Generate again for another batch.
