In the world of web development and prototype testing, having placeholder data is essential. It allows developers to create and test their applications without the need for real data. One popular tool for generating dummy or fake JSON data is Project DummyJSON.

What is Project DummyJSON?

Project DummyJSON is a free online tool that helps developers generate dummy JSON data quickly and easily. It provides a simple and intuitive interface where users can define the structure and content of their JSON data.

How does Project DummyJSON work?

Using Project DummyJSON is straightforward. Here’s a step-by-step guide:

  1. Visit the Project DummyJSON website at
  2. On the homepage, you’ll find a text area where you can define the structure of your JSON data using a simple syntax.
  3. Specify the number of data objects you want to generate.
  4. Click the “Generate JSON” button.
  5. The generated JSON data will be displayed in the text area below.
  6. You can then copy the generated JSON data and use it in your development or prototype testing.

Customizing the Dummy JSON Data

Project DummyJSON allows you to customize the dummy JSON data according to your needs. Here are a few ways you can do this:

1. Defining the Structure

You can define the structure of your JSON data using the simple syntax provided by Project DummyJSON. This includes specifying objects, arrays, properties, and their respective values.

2. Generating Multiple Objects

If you need multiple data objects, you can specify the number of objects you want to generate. Project DummyJSON will create the specified number of objects with the same structure.

3. Adding Randomness

Project DummyJSON allows you to add randomness to your dummy JSON data. You can use predefined keywords like __randomNumber__, __randomString__, and __randomBoolean__ to generate random values for your properties.

4. Customizing Property Values

You can customize the values of your properties by using predefined keywords and functions provided by Project DummyJSON. For example, you can use __firstName__ to generate a random first name or __date__ to generate a random date.

Benefits of Using Dummy JSON Data

Using dummy JSON data in development and prototype testing offers several benefits:

1. Faster Development

By using dummy JSON data, developers can focus on building the application logic without waiting for real data. This speeds up the development process and allows for quicker iterations.

2. Simulating Real Scenarios

Dummy JSON data can be used to simulate real-world scenarios and test the application’s behavior under different conditions. This helps identify and fix potential issues early on.

3. Data Privacy

Using dummy JSON data ensures that sensitive or private information is not exposed during development or testing. This is particularly important when working with user data or confidential information.

4. Scalability Testing

With dummy JSON data, developers can test the scalability of their applications by generating large amounts of data. This helps identify any performance bottlenecks and optimize the application accordingly.


Project DummyJSON is a valuable tool for developers and testers who need dummy or fake JSON data for development and prototype testing. Its simple interface and customization options make it easy to generate placeholder data that closely resembles real data. By using dummy JSON data, developers can streamline the development process, simulate real scenarios, maintain data privacy, and test scalability. Give Project DummyJSON a try and experience the benefits it offers!
