API Mock Data Generator
Generate realistic mock API response data from a JSON schema or sample JSON. Includes built-in Chinese names, emails, phone numbers, and addresses.
Frontend developers often need to build UI against an API that does not exist yet. Instead of waiting for the backend team or hardcoding dummy values, you can generate realistic mock data to iterate on your components immediately. This tool takes a sample JSON or simple schema and produces multiple records of plausible data with correct types and structure.
The generator includes a built-in localization library with over 50 common Chinese names, realistic email domains, Mainland China mobile numbers, city names, and street addresses. It handles nested objects, arrays, numeric ranges, date formats, boolean values, and more. Generate between 1 and 100 records and export the result as formatted JSON ready to paste into your mock server or test fixtures.
