100% Client-Side Generation

Multi-Format Export

Export instantly as formatted JSON, NDJSON (JSON Lines), SQL INSERT statements, CSV, or auto-generated TypeScript interfaces.

Rich Realistic Seed Dictionaries

Includes realistic names, emails, companies, job titles, UUIDs, dates, currencies, addresses, and customizable status enums.

Frequently Asked Questions

How many rows can I generate at once?

You can generate anywhere from 1 to 1,000 records instantaneously in your browser. The data is created dynamically in RAM without server rate limits or lag.

Can I generate custom enumerated choices (e.g. active, inactive)?

Yes. Choose the "Custom Options / Enum" field type and provide a comma-separated list like "active, pending, suspended, archived". The generator will randomly pick from your choices.

How do SQL INSERT statements work?

When selecting the SQL export format, you can specify your database table name. The tool automatically escapes quotes and generates valid ANSI SQL insert queries suitable for PostgreSQL, MySQL, and SQLite.

Can this replace Mockaroo or Faker.js?

Yes, for standard front-end prototypes, API mocking, database seeding, and unit testing, this tool provides instant zero-latency generation with zero account creation or paywalls.
