Gerador de dados fictícios
Gera JSON fictício realista para testes e protótipos
Fields to include:
Generated Data
Generate realistic test data without writing fixtures
Hand-written fixtures get stale, repeat themselves, and never cover the edge cases that show up in production. Generating mock data from a schema produces dozens or hundreds of realistic records — names, emails, dates, prices, addresses — so you can prototype UI, load-test endpoints, and seed local databases without touching real customer data.
Use the generator when you need to
Seed a local database for development
Generate hundreds of users, orders, or products and import them once instead of typing fixtures by hand.
Build UI before the backend is ready
Mock the API response shape so your frontend can iterate on layouts, empty states, and edge cases.
Load-test or stress-test an endpoint
Generate large payloads to validate pagination, sorting, and rendering under realistic data volumes.
How to generate mock data
- 1
Define field names and pick types (name, email, address, date, etc.) in the schema builder.
- 2
Set the number of records you want.
- 3
Click Generate and copy or download the resulting JSON array.
Keep going
Generate a schema from real data
Lift the schema from a sample response and use it to drive mock generation.
Type the mock data
Generate TypeScript interfaces for the mock structure so your code stays type-safe.
Export mock data as CSV
Convert generated records to CSV for use in spreadsheets or bulk imports.
Format the output
Beautify generated arrays before pasting into fixtures.
Common mock data workflows
Generate 200 user records to validate how the table behaves with realistic names and emails.
Seed a fresh database with believable data for a sales demo without touching production.
Generate edge-case data (empty strings, very long names, far-future dates) to surface a bug consistently.

Defina a estrutura dos dados no construtor de schema — escolha nomes e tipos de campos (name, email, address, number, date etc.) e a quantidade de registros. Clique em Generate para criar dados de teste com aparência realista instantaneamente.
O gerador suporta nomes, emails, telefones, endereços, nomes de empresas, cargos, datas, UUIDs, URLs, endereços IP, cores, nomes de produtos, preços e texto lorem ipsum — mais de 50 tipos de dados usando a biblioteca Faker.js.
Sim. Os dados mock são feitos para desenvolvimento e testes. Use para popular bancos, testar endpoints de API, preencher componentes de UI ou montar ambientes de demo. Os dados parecem reais, mas são totalmente fictícios.
Você pode gerar até alguns milhares de registros de uma vez. A ferramenta roda no seu navegador, então a performance depende do seu dispositivo. Para casos típicos (10–500 registros), a geração é instantânea.
