Fields to include
This bulk fake data generator creates many fictional identities at once and exports them to CSV, JSON, or SQL INSERT statements. Pick how many records you need, choose your fields, and download a file you can drop straight into a test database or spreadsheet.
Every record is fictional and safe for testing: addresses pair real cities with valid ZIP codes and randomized house numbers, national IDs are masked test placeholders, and credit-card numbers come from sandbox test ranges. Nothing describes a real person and nothing can charge a real account.
Each format is shaped for where it usually lands. The CSV export starts with a header row naming your selected fields, so it opens cleanly in a spreadsheet and imports directly with tools like Postgres COPY. The JSON export is a plain array of objects, ready for a fixtures file or an HTTP mock. The SQL export is a ready-to-run set of INSERT statements, so seeding a development table is paste-and-execute. In every format, only the fields you selected are included — there are no hidden columns to strip afterwards.
One property of any realistic dataset surprises people at scale: duplicates. Random draws collide far earlier than intuition says — the birthday paradox — and we measured it on this engine: across 2,000 US profiles, the first repeated first name arrived at profile 14 and the first repeated full name at profile 599. That is a feature for most tests, because real customer tables contain people who share a name or a birthday, and code that silently merges them is exactly the bug realistic data catches. Deduplicate only the columns your schema genuinely requires to be unique, like emails or usernames, and let display fields stay realistic.
It is completely free, with no sign-up and no cap behind a paywall — export up to 100,000 records in one file. Generation runs entirely in your browser, so the data never leaves your device.
Frequently asked questions
How many records can I generate?+
Up to 100,000 records per export, completely free and with no sign-up. Everything is generated in your browser, so nothing is uploaded or stored.
What export formats are supported?+
CSV, JSON, and ready-to-run SQL INSERT statements. You can choose exactly which fields to include in every format.
Is the bulk data safe to use in a test database?+
Yes. Every record is fictional: addresses use valid ZIP codes with randomized house numbers, national IDs are masked test placeholders, and card numbers are sandbox test numbers. No record describes a real person.
Is the generated dataset reproducible?+
Not from this page — each download mints a fresh internal seed, so pressing Generate twice gives two different datasets. The engine underneath is fully deterministic, so if you need a fixture you can commit and regenerate exactly, call the JSON API with your own ?seed= value instead. Either way the exported file itself is stable once you have downloaded it.
