Frequently Asked Questions
What does JSON Comparison do?
It deep-compares two JSON objects and shows every key that was added, removed, or changed between them — including nested keys inside objects.
Does it support nested objects?
Yes — ByteKit recursively compares all nested objects and arrays, showing the full key path (e.g. address.city) for deeply nested differences.
Is my JSON data private?
Yes — comparison happens entirely in your browser using JavaScript. Your JSON data is never sent to any server.
Can I compare JSON arrays?
Yes — arrays are compared element by element. Added and removed elements are highlighted. For best results wrap arrays in an object key.
