Where can I find a detailed description of "explain format=json"?

Question

MySQL

Is there somewhere a complete description of what this operator will return? I just need to deserialize it, but I don't know how to create a class, because SELECTs are different: Somewhere there is, for example, GROUPING and somewhere it is not... And you don't know for sure...
