Generate mock arrays, objects, and utility data for testing, APIs, and UI design. Developer-ready online tool for structured sample data creation. Fast, flexible, and free.
Use regex patterns to generate custom formatted data. Examples: [A-Z]3[0-9]3 for ABC123, \d4-\d2-\d2 for dates like 2024-01-15
Maximum: 5,000 rows

Generate custom CSV and JSON test data with unlimited columns and data types. Perfect for database testing, software development, API testing, and data analysis. Create realistic fake data including names, emails, addresses, phone numbers, financial data, and more for your testing needs.
An array data generator or object data generator is a tool that produces structured values formatted as arrays and objects. Instead of writing manual entries, you can use the FakerBox mock array data and mock object data generator to:
The tool is developer-friendly and adapts to multiple scenarios, making it valuable for testing, prototyping, and demos.
Using an array data generator saves time by creating arrays and objects instantly.
Mock object data prevents the exposure of sensitive or real information during development.
The object data generator creates realistic key-value pairs and structured arrays that look like production-ready data.
You can create mock array data for forms, dashboards, and APIs, while mock helper functions support educational and training use cases.
Select from fields such as array element, object key, object value, or shuffle array.
Click Generate to create results such as:
Advanced users can apply regex rules to format array elements or object values with custom rules, such as enforcing length or naming conventions.
Copy single arrays and objects for quick testing or export bulk mock array data and mock object data in CSV or JSON formats for large-scale workflows.
Use the array data generator to create structured mock data for APIs, dashboards, and testing.
Teach programming and data structure concepts with mock object data and fake utility data.
Simulate experimental datasets using shuffled arrays and key-value pairs.
Fill user interfaces with mock helper functions and dummy helper functions to make prototypes look realistic.
Use mock array data to simulate examples in tutorials or technical writing.
It is a tool that creates arrays of sample data elements for testing and demos.
