How to use Randomize a JSON Object
- 1. Paste your JSON object. Put the JSON object into the input pane. The key-value pairs themselves are untouched; only the order they appear in gets randomized.
- 2. Decide whether to shuffle nested objects. Turn on Shuffle nested objects too so any objects living inside the top-level object also get their pair order scrambled, rather than only the outermost one.
- 3. Pick an indent. Choose 2 spaces, 4 spaces or tabs to control how the shuffled object is formatted before you copy it out to wherever it needs to go.
- 4. Copy the shuffled object. Copy the reordered object and use it to check that downstream code handles JSON objects correctly regardless of the order their properties happen to appear in.
When to use Randomize a JSON Object
Randomize a JSON Object shuffles the order of an object's key-value pairs while leaving each pair's content untouched. It exists for testing whether code silently depends on property order, something the JSON spec never guarantees in the first place.
- Verifying a serializer's assumptions. You suspect a custom serializer relies on keys appearing in a specific order to work correctly. Randomize the input object and confirm the serializer still produces the right result.
- Testing object iteration bugs. A bug only reproduces when object keys are iterated in a certain sequence, and you want to rule that out. Shuffle the object repeatedly and rerun the code against each variant.
- Generating varied-looking fixtures. You need several test files with the same data but different visual layout to make sure a diff or comparison tool isn't fooled by superficial reordering.
- Confirming a diff tool ignores order. Before trusting a JSON diff tool's Ignore key order setting, shuffle a known object and check the diff still reports no meaningful differences between the two versions.

}About the Randomize a JSON Object tool
Randomize a JSON Object is a free online tool that works entirely inside your web browser. Shuffle the order of key-value pairs in a JSON object. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 90 JSON utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Shuffle nested objects too and Indent, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Randomize a JSON Object free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
