Mock JSON data generator from a sample
UI work dies when every row is { "name": "Test" }. This generator reads a sample object, infers emails, names, IDs, prices and dates from field names, and builds an array of records.
Paste one example, set the count, copy the JSON into MSW, a Laravel factory preview or Storybook. Review the output; inference is heuristic.
Do not use inferred personal data as real user information. It is fake and may still look identifiable.
