JSON diff compares two JSON objects and highlights every difference — added keys, removed keys, and changed values. Essential for API versioning, config file reviews, and debugging data changes.
Paste two JSON objects separated by a blank line, then click Compare. Green shows additions, red shows removals, orange shows changes. All processing is browser-based and private.
It recursively compares every key and value in both objects. Matching keys with different values show as changed. Keys in only one object show as added or removed.
Yes — the diff tool recursively descends into nested objects and arrays, showing the full path to each difference using dot notation.
