Test Data Generator

A test data generator produces realistic fake rows for development and QA — names, emails, dates, UUIDs and addresses — without touching production data. Defining columns and a row count gives you a dataset that looks plausible in a UI while carrying no real personal information.

What does a test-data generator produce?

A test-data generator creates multiple structured rows from a chosen column schema, giving developers and QA teams realistic-looking fixtures without copying production records. Available field types include names, emails, integers, booleans, dates, UUIDs, and addresses, with export suitable for common test workflows.

Generation uses @faker-js/faker in the browser and PapaParse for tabular export. Values are plausible but not relationally consistent, unique, or guaranteed to satisfy an application's validation rules. Seeded, referential, or regulated test datasets still need purpose-built fixtures and explicit constraints.
