Sort JSON object keys alphabetically across nested objects for cleaner and more stable output.
Use this JSON Sort Keys tool to reorder JSON object keys alphabetically, including nested objects. It is useful for cleaner diffs, more stable snapshots, documentation, config cleanup, and preparing JSON for review when object key order is inconsistent. The tool preserves values and array order while sorting object keys recursively.

Use json sort keys when you need a fast browser-based result without extra setup. It works well for quick checks, one-off tasks, and routine formatting or calculation work.

Input
{"b":2,"a":1} Output
{
"a": 1,
"b": 2
} Useful when a small object has inconsistent key order.
Input
{"user":{"name":"Anna","id":7},"meta":{"z":1,"a":2}} Output
{
"meta": {
"a": 2,
"z": 1
},
"user": {
"id": 7,
"name": "Anna"
}
} Useful when nested payloads need stable ordering for review or version control.
Fix: This tool sorts object keys only. It preserves the original order of array items.
Fix: Validate or format the JSON first before sorting keys.
Fix: Sorting keys only changes object key order. Values and meaning stay the same.
Fix: This tool only reorders keys. It does not merge, rename, or normalize fields.
Fix: Use JSON Minifier if you want compact output after sorting.
It sorts JSON object keys alphabetically, including nested objects.
No. Array item order stays the same.
No. It only changes object key order.
Because stable key order reduces unnecessary diff noise when the same data is represented with different object ordering.
Formatter improves readability, while Sort Keys also normalizes object key order recursively.
