Custom Test Data Generator Tool

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.

What Is an Array & Object Data Generator?

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:

  • Generate array elements for sample datasets
  • Create mock object data for APIs and applications
  • Shuffle arrays to simulate randomized structures
  • Use fake utility data for building mock helper functions

The tool is developer-friendly and adapts to multiple scenarios, making it valuable for testing, prototyping, and demos.

Why Use Mock Array and Object Data?

Efficient for Development

Using an array data generator saves time by creating arrays and objects instantly.

Safe for Testing

Mock object data prevents the exposure of sensitive or real information during development.

Authentic and Structured Outputs

The object data generator creates realistic key-value pairs and structured arrays that look like production-ready data.

Versatile Applications

You can create mock array data for forms, dashboards, and APIs, while mock helper functions support educational and training use cases.

How to Generate Arrays and Objects with FakerBox?

Pick Your Fields

Select from fields such as array element, object key, object value, or shuffle array.

Generate Arrays and Objects

Click Generate to create results such as:

  • Array Element: [“apple”, “banana”, “cherry”]
  • Object Key: username
  • Object Value: johndoe_123
  • Shuffle Array: [“cherry”, “apple”, “banana”]

Regex Options

Advanced users can apply regex rules to format array elements or object values with custom rules, such as enforcing length or naming conventions.

Save Your Outputs

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.
