JSON Diff FAQ
How does the comparison work?
The tool recursively compares both JSON documents, checking each key and value. It identifies properties that exist only in one document (added/removed) and properties with different values (changed).
Can it compare large JSON files?
Yes, the tool handles large JSON documents efficiently. For very large files (over 5MB), comparison may take a few seconds.
Is my data secure?
Absolutely! All comparison happens directly in your browser using JavaScript. Your JSON data is never sent to any server.
