How to sort JSON keys
Paste a valid JSON object or array, choose ascending or descending order, then sort. Object keys are sorted recursively; array item order is intentionally preserved because arrays are ordered data.
Why sort JSON
Sorting is useful when comparing generated configs, snapshots, and API examples where key order changes make reviews noisy. Use the JSON Compare tool after sorting for cleaner diffs.
