JSON Sort - Sort JSON Object Keys Alphabetically

Sorted Output

What is JSON Sort?

Ever opened a JSON file and thought "why are these keys in such a random order?" This tool fixes that. It sorts all your JSON (JavaScript Object Notation) object keys alphabetically, making everything way easier to read and compare.

As MDN Web Docs points out, key order doesn't affect how JSON works, but sorted keys make life so much easier. Our tool sorts everything alphabetically while keeping all your data intact. We follow the RFC 8259 JSON specification, so you know it's legit.

Everything happens in your browser – your JSON never leaves your computer. Sort it, organize it, and get back to work.

How to Use JSON Sort

Follow these steps to sort JSON object keys alphabetically. Each step uses the actual buttons and panels on this page.

Paste JSON or Upload File

Paste your JSON into the left Input panel, or click Upload to load a .json or .txt file. Click Sample to see example unsorted JSON. Example input:

{"carrier": "Verizon", "subscriberId": "SUB-1001", "plan": "5G"}

Output becomes {"carrier": "Verizon", "plan": "5G", "subscriberId": "SUB-1001"} – keys sorted A–Z. Valid per RFC 8259.

View Sorted Output

The right Sorted Output panel shows the result automatically. Keys are sorted alphabetically at every level – nested objects are sorted recursively. Values stay unchanged; only key order changes. Great for cleaner Git diffs and easier comparison.

Copy or Download

Click Copy to copy the sorted JSON to your clipboard, or Download to save as a file. Use Clear on the input panel to start over. All processing runs in your browser.

When You'd Actually Use This

Version Control

Sort JSON keys before committing to Git. Makes diffs cleaner and easier to review, reducing noise from key reordering.

Comparison

Sort JSON objects before comparing them. When keys are in the same order, differences are easier to spot.

Config Files

Organize configuration files for better readability. Sorted keys make it easier to find and edit specific settings.

Easier Navigation

Find properties faster in large JSON objects. Alphabetical order makes it easier to locate specific keys.

Common Questions

Is my JSON data stored?

No. Sorting happens entirely in your browser using JavaScript. Your data never leaves your computer. Check out the ECMA-404 standard for more details.

Does sorting affect JSON functionality?

No. JSON object key order doesn't matter for functionality. Sorted JSON works exactly the same as unsorted JSON – it's just more organized. Check out the RFC 8259 for more details.

What about arrays?

Arrays are not sorted – only object keys are sorted. Array element order is preserved. If you have an array of objects, each object's keys are sorted.

Are nested objects sorted?

Yes. The tool recursively sorts keys in all nested objects. Every level of nesting gets sorted alphabetically.

What if my JSON is an array?

If your JSON is an array of objects, each object's keys will be sorted. The array order itself is preserved.

Does it work with invalid JSON?

No. The input JSON must be valid. If it's invalid, you'll see an error. Use our JSON Validator or JSON Fixer first.

Other JSON Tools You Might Need

Sorting is just one JSON task. Here are other tools that work well together:
