How to assert grpc method response body

I'm verifying response of a grpc service method. Right now im asserting response by taking out every parameter and verifying it against my expected test parameter.If there are many parameters to assert, it becomes a tedious process. So im looking for something like 'Json comparator' which will verify my grpc response message with expected message .

I'm also thinking of converting my expected and my actual messages to json and verifying it using json comparator.But this is not straightforward. So any other thoughts?
