JSON Sorter
Normalize JSON key order for cleaner diffs, code reviews, and deterministic fixtures without uploading data.
Input
Paste JSON to sort object keys
Sorted output
JSON with recursively sorted object keys
Paste valid JSON, choose an order, then sort the keys.
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.
What this JSON Sorter does
Use this JSON sorter to alphabetize object keys recursively for cleaner diffs and deterministic snapshots. Sorting keys makes generated JSON easier to review in pull requests and test fixtures.
When developers use it
- Normalize JSON before comparing files in Git or code reviews.
- Sort nested API responses, configuration objects, and fixture data.
- Prepare deterministic output for tests that compare JSON strings.
Privacy, input, and output
Sorting happens in browser memory only. PayloadHarbor does not store or upload the JSON document.
Paste valid JSON and run the sorter. The output preserves values while recursively ordering object keys; arrays keep their original item order.
Validation rules and limitations
- Input must be valid JSON.
- Only object keys are sorted; array entries are not reordered because that can change meaning.
