About JSON Merge Patch

JSON Merge Patch (RFC 7396) is a simple format for describing changes to a JSON document. Unlike JSON Patch (RFC 6902), a merge patch is itself a JSON object that mirrors the target document — fields present in the patch replace the corresponding fields in the original, and fields with a null value are deleted. Fields absent from the patch are left untouched. Use the Generate Patch tab to compute the minimal merge patch between two objects, or the Apply Patch tab to apply an existing patch to a document. All processing happens entirely in your browser — no data is sent to any server.
