Can json flatten spec create multiple rows from single json object?

if i have an object like:

{

host: “myhost”

metrics: [

{ name: "metric1", value: 100},

{ name: "metric2", value: 200}

]

}

Can json flatten spec be used to convert it to 2 rows like:

host: “myhost”, metric: “metric1”, value: 100

host: “myhost”, metric: “metric2”, value: 200
