This is exactly what I was looking for. Feature request: A preview on how the found entities would look like on Google. Do you think something like that would be possible?

Works great for offline pages as well.

Just what I was looking for! It quickly shows the JSON LD on any site without the hughe query time that the Google JSON LD test tool requires. Perfect for tweaking your JSON LD!
