About Fake Data Generator

Generate massive datasets of realistic dummy data for testing and development. Build custom schemas with fields like names, emails, and credit cards. Export up to 5,000 rows instantly as JSON, CSV, or SQL INSERT statements to seed your database.

Under the Hood

Data generation is powered by `@faker-js/faker`, which provides localized data providers for names, addresses, and commerce items. The tool builds an array of objects based on the user-defined schema. Exporting involves transforming this in-memory array: `JSON.stringify` for JSON, a custom string builder for CSV (handling escaping), and a SQL INSERT statement generator that maps JS types to SQL types (e.g., Dates to ISO strings, text to quoted strings).
