A: A mock data generator is a tool that creates realistic fake data for testing and development purposes. It generates data that looks authentic but doesn't contain any real personal information, making it safe for testing applications, databases, and APIs.
A: No! Our tool is completely free and doesn't require any registration. Simply visit the website and start generating data immediately.
A: Yes, 100% free with no hidden costs, subscriptions, or usage limits. We believe every developer should have access to quality testing tools.
A: All data generation happens entirely in your browser using JavaScript and the Faker.js library. You define a JSON schema with the data types you need, and our tool generates realistic data matching that structure.
A: Absolutely safe! All data generation happens locally in your browser. We never store, transmit, or access your schemas or generated data. Your information never leaves your device.
A: The generated data is completely fake and safe to use for testing. However, we don't recommend using mock data in production environments - it's designed for development and testing only.
A: We only collect anonymous analytics data (like page views) to improve our service. We don't collect, store, or process any of the schemas or data you generate. See our Privacy Policy for details.
A: We support over 60 different data types including names, emails, phone numbers, addresses, dates, UUIDs, prices, product information, and much more. Check the data type reference panel for the complete list.
A: A schema is a JSON object that defines the structure of your data. Each key represents a field name, and the value is the data type. For example: {"name": "name", "email": "email", "age": "number"}
A: No, data types are case-insensitive. You can use 'email', 'Email', or 'EMAIL' - they all work the same way.
A: Currently, the tool generates flat JSON objects. Each record is a single-level object with your defined fields. For complex nested structures, you may need to generate separate datasets and combine them manually.
A: If the generator doesn't recognize a data type, it will generate a random word as a fallback. Make sure to check the data type reference panel for correct type names.
A: You can generate up to 1,000 records in a single generation. This limit ensures good performance and prevents browser slowdowns.
A: No, there are no daily limits. Generate as much data as you need, whenever you need it.
A: The initial page load requires an internet connection, but once loaded, the data generation works offline since everything runs in your browser.
A: Yes! Our tool is fully responsive and works on smartphones and tablets, though the experience is optimized for desktop use.
A: All data is generated in JSON format, which is widely compatible with most programming languages, databases, and APIs.
A: You can either copy the JSON to your clipboard with one click or download it as a .json file. Both options are available in the data viewer panel.
A: Absolutely! The JSON format is perfect for API testing. Copy the generated data and use it in tools like Postman, Insomnia, or directly in your API tests.
A: Most databases can import JSON data. For MongoDB, you can use mongoimport. For SQL databases, you may need to convert JSON to SQL INSERT statements or use database-specific import tools.
A: This error appears when your schema is not valid JSON. Check for missing commas, quotes, or brackets. Make sure your JSON is properly formatted with correct syntax.
A: Make sure you're using the correct data types. For example, use 'name' instead of 'text' for person names, 'email' for email addresses, etc. Check the data type reference for appropriate types.
A: Currently, each data type has a predefined format. We use standard formats that work in most scenarios. Custom formatting options may be added in future updates.
A: Our tool works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for the best experience.
