About Mock Data Generator
The Mock Data Generator allows you to instantly generate realistic JSON data for testing APIs, populating databases, or mocking UI components. It leverages standard faker data to ensure your prototypes look like real-world applications.
How to Use
Real-World Examples
Mocking a User API Endpoint
Generate 100 records containing UUIDs, realistic names, avatars, and email addresses to test a pagination component.
Schema: id (UUID), name (Full Name), email (Email)
[
{ "id": "123e4567-e89b-12d3...", "name": "Jane Doe", "email": "jane@example.com" }
]Best Practices
- Use realistic mock data to catch UI overflow bugs early (e.g., generating very long names or addresses).
- Generate a large dataset (1,000+ rows) to test the performance of your data tables and virtualized lists.
Pro Tips
You can export directly to CSV if you need to load the mock data into Excel or a traditional SQL database.
Frequently Asked Questions
Can I define custom nested schemas?
Currently, the generator outputs flat JSON arrays. For nested schemas, we recommend generating relational flat files and combining them programmatically.
Is my data secure?
Absolutely. All processing is done locally in your browser. Your data is never sent to our servers.
Security & Privacy
All data is generated locally using client-side JavaScript. No external API calls are made, and your custom schemas remain entirely private.
