Frequently Asked Questions
It detects four types of differences: key additions, key deletions, value changes, and type changes (e.g., string to number). It recursively compares nested objects and arrays.
Yes, arrays are compared by index, so the same elements in different orders are shown as changes. Sort the arrays first if order-independent comparison is needed.
Null is treated as an independent type. Changes from null to another value are classified as type_changed.
It depends on browser memory. Typically JSON files of several MB can be compared smoothly. Very large files may cause slower responses.
Standard JSON does not support comments, so parsing errors will occur if comments are included. JSON5 format is not supported.
