Using Fake Data & Mock Generator

Choose a template or define up to 40 fields, set null probabilities and a locale, then generate 1–1,000 rows. After the first generation, edits regenerate the preview; output format changes retain the same data. Faker locales load on demand with English fallbacks for missing definitions. SQL uses standard quoted identifiers; review your database dialect before executing. CSV nulls become empty cells and optional formula protection prefixes risky strings. Names, contact details, financial identifiers, and passwords are synthetic test data, not verified identities or secure credentials. No schema or generated records are uploaded.
