Frequently Asked Questions
What types of JSON differences can be detected?
Our JSON Compare tool detects: added keys, removed keys, modified values, type changes (string→number, array→object), and nested structure differences. Changes are color-coded: green for additions, red for deletions, yellow for modifications.
Can I compare large JSON files?
Yes! Our tool can handle JSON files up to 10MB. The comparison runs entirely in your browser, so there's no upload limit or server delay. Perfect for comparing API responses, config files, or database exports.
Does it handle JSON arrays?
Absolutely. Arrays are compared element-by-element, with index-level differences shown. You can also toggle 'ignore array order' mode to compare arrays as sets, which is useful when element order doesn't matter.
