Frequently Asked Questions — Mock JSON Generator
Q1: What is mock JSON data?
Mock JSON data is realistic but fake data used for development, testing and prototyping. It has the same structure as real data but contains generated values instead of actual user or business information.
Q2: Can I use mock data in production?
No. Mock data is for development and testing only. Never use fake or generated data in a live production environment as it could mislead users and violate data integrity requirements.
Q3: How many records can I generate at once?
Our free tool supports generating up to 1000 records in a single operation. For bulk data generation beyond this limit, consider our API (coming soon) or split your generation into multiple batches.
Q4: Can I customise the mock data templates?
Yes. Our Custom template lets you define your own fields and data types. You can specify field names, types (string, number, boolean, date, email, UUID) and nesting structure.
Q5: Is the generated data truly random?
Yes. Each time you generate data, new random values are created. Names, emails, addresses and other fields use realistic patterns so the data looks authentic in your UI.
Q6: Can I use this for database seeding?
Yes. Mock JSON data is perfect for seeding development and staging databases. You can generate the data, download it as JSON and import it using your database tooling or ORM seed scripts.
