About Custom Mock Data Generator
The Custom Mock Data Generator is a powerful, privacy-first tool designed for software developers, testers, and designers who need realistic sample data to populate databases, test API endpoints, or design layouts. You can easily define your schema by choosing from a variety of data types, customize format configurations, and choose the number of records to generate. Export the generated data instantly to JSON, CSV, or SQL insert statements. The tool dynamically adjusts its data generation options based on the selected language, offering localized data such as CPF, CNPJ, and CEP for Brazil, SSN and ZIP Codes for the United States, and DNI or Spanish Postal Codes. All data generation is processed locally in your browser, ensuring absolute security for your schema layouts.
