Is the data realistic?

Field types draw from curated name, email, date, and other generators so the output looks plausible — ideal for UI demos and seed data, though it is entirely fictional.

Can I import it into a database?

Yes — choose the SQL format to get ready-to-run INSERT statements with your chosen table name, or use CSV for bulk import tools.

Mock / Fake Data Generator

Build realistic fake datasets for testing, demos, and database seeding. Define your fields — names, emails, UUIDs, dates, numbers, and more — choose a row count, and export as JSON, CSV, or SQL insert statements. Everything is generated locally.

How to use Mock / Fake Data Generator

Add fields and pick a data type for each.
Set how many rows you want.
Export as JSON, CSV, or SQL — copy or download.
