Use the toggles to decide what kind of values you want: numbers, strings, or booleans. The JSON output updates live in the right-hand box, complete with a character count. When you’re done, hit “Copy Output” or “Export to File” to save it. Or tap “Clear All” to reset and start fresh.

What Create a Random JSON Object can do:

Create a Random JSON Object helps you build quick, valid mock data for testing, demos, or prototyping. It gives you control over how many keys to generate and what kind of values they contain. Turn numbers off, leave booleans on, or mix them all. The result is a clean JSON object you can paste straight into code, config files, or anywhere else you need some dummy content. You don’t need to write a single line it’s just click, tweak, and go.

Example:

Settings:

  • 4 keys
  • Include strings and booleans only

Output:

{
  "key1": "tv3u1x",
  "key2": false,
  "key3": "slk09q",
  "key4": true
}

Common Use Cases:

Whether you’re building UI layouts, simulating API responses, or filling test cases, Create a Random JSON Object saves you time. It’s perfect for frontend mocks, placeholder datasets, or throwing together example content in seconds. Developers, designers, and QA folks can all use it to skip the boring part of making test data.

Useful Tools & Suggestions:

After generating a random object, Stringify JSON can be used to turn it into a clean string for storage or transmission. And if you want to mix things up a bit more, Randomize a JSON Object helps shuffle the keys and values around.
