Tips & Best Practices
- Use the generated SQL INSERT output as seed data for test databases.
- JSON output is one array of objects, ready to drop into a fixture file or a fetch() mock response.
- CSV output uses double-quote escaping (RFC 4180) — Excel and pandas read it without preprocessing.
- Email generation combines a randomly chosen first/last name with a sequential integer to keep entries unique across batches.
- Need a specific record? Increase the count, generate, then trim to the rows you want.
