Test Data Generator

No — test data is intentionally fake and should only be used in development, staging, or automated test environments. Never seed a production database with generated records, as names, emails, and phone numbers are fabricated from static arrays and do not belong to real people.

No. All data generation happens entirely in your browser using a seeded pseudo-random number generator (PRNG). No network requests are made, nothing is logged, and no generated data ever leaves your machine.

The password field generates a bcrypt-style placeholder string in the format $2b$NN$<53-char-hash>. This mimics the output of real bcrypt hashing libraries (like bcryptjs or passlib) but is not a real hash — it is just a realistic-looking placeholder for UI and schema testing.

CSV and SQL formats require flat key-value rows with no nested objects. When the address field is selected, it is automatically expanded into four separate columns: address_street, address_city, address_state, and address_zip. JSON and TypeScript outputs preserve the nested address object.

The SQL output generates a single INSERT INTO users (...) VALUES ... statement. Copy it directly into your database client (psql, MySQL Workbench, DBeaver, etc.) and run it. You may need to rename the table or column names to match your actual schema. Column types should be VARCHAR or TEXT for most fields, INTEGER for age.

The tool caps at 100 records per generation to keep the browser UI responsive. If you need thousands of records, generate in multiple batches and concatenate the output files, or use a server-side library like Faker.js (Node.js) or Faker (Python) for large-scale datasets.
