How to use

  1. 1 Define a JSON schema — each leaf value is a faker.js dot-path like person.fullName, internet.email or number.int({min:18,max:65}).
  2. 2 Set the count slider (1–1000) and pick an output format: JSON, CSV, TSV or XML.
  3. 3 Hit Generate to produce random records. Re-roll any time for new values.

Why use this tool

  • Schema-driven — your fields stay yours, only the values are randomized.
  • Powered by @faker-js/faker — modern, locale-aware, hundreds of generators.
  • Faker bundle is lazy-loaded — page is light until you click Generate.
  • Output to JSON, CSV, TSV or XML — drop straight into a database seeder or test fixture.

Frequently asked questions

What dot-paths can I use?

Anything under <code class="font-mono text-xs">faker.*</code> — for example <code class="font-mono text-xs">person.firstName</code>, <code class="font-mono text-xs">company.name</code>, <code class="font-mono text-xs">finance.iban</code>, <code class="font-mono text-xs">date.past</code>. See the faker.js docs for the full list.

Can I pass arguments?

Yes — wrap the argument object in parentheses. Example: <code class="font-mono text-xs">number.int({min:1,max:100})</code> or <code class="font-mono text-xs">helpers.arrayElement(["a","b","c"])</code>.

Where does the data come from?

Everything runs in your browser — faker.js generates locally, no API calls. Your schema and data never leave your device.
