Frequently Asked Questions
What types of JSON differences are detected?▾
The tool finds added keys, removed keys, changed values, type differences, and nested object/array changes at any depth.
Can I compare large JSON files?▾
Yes. The diff engine handles files with thousands of keys efficiently. Processing happens entirely in your browser.
Does key order matter for the comparison?▾
No. JSON objects are unordered by specification, so the tool compares by key name regardless of position.
