JSON Sort Keys

Paste any JSON and reorder its object keys. By default the sort is applied recursively across all nested objects and pretty-printed. Optionally make it case-insensitive, sort descending, or enable numeric-aware ordering so that `item2` sorts before `item10` (via Intl.Collator). Sorted JSON is useful for stable diffs, lockfile comparisons or canonical hashing. Runs entirely in your browser — free, online, no upload.
