Mock Data Generator

Generate realistic JSON mocks with Faker templates — names, emails, cards, geo, and more. Export JSON or CSV in-browser.

Formatters & Utilities
Privacy: 100% Client-Side. Your data never leaves this browser tab. Processing uses Web APIs and client-side libraries only.

Generate realistic JSON with @faker-js/faker entirely in your browser. Use {{module.method}} tokens — e.g. {{person.fullName}}, {{internet.email}}, {{string.uuid}}.

Why generate mock data locally?

UI demos, API stubs, and QA scripts need realistic sample records without hitting production databases or third-party mock APIs.

stbox runs @faker-js/faker in your browser. Paste a JSON template with {{module.method}} placeholders, choose a count, and export JSON or CSV — nothing is uploaded.

How to use this tool

  1. Pick a preset or edit the JSON template with {{person.fullName}}-style tokens.
  2. Set count (1–1000) and optional seed, then Generate JSON.
  3. Copy JSON or Export CSV for spreadsheets and fixtures.

Frequently asked questions

Is Faker running on a server?

No. @faker-js/faker is bundled and executed entirely in the browser.

Can I reproduce the same dataset?

Yes — set a numeric seed before generating to get deterministic output for that session.
