Frequently asked questions

＋What kind of data is generated?

An array of user-style objects with id, name, email, a random USD balance and an active flag — great generic seed data.

＋Can I use this in production?

It's meant for testing and prototypes. The values are randomized and not tied to real people.

＋How many records can I generate?

From 1 up to 100 records per run. Copy the JSON directly into your fixtures or mock API.
