JSON feeder: how to read JSON Object?

Hi,
I want to use a feeder to read a JSON file. My JSON looks like:

[

{

“id”:19434,

“bar”: {

“baz”: 1

}

},

{

“id”:19435,

“bar”: {

“qux”: “quux”

}

}

]

I know how to read a string, number or a boolean (i.e.: id) in my scenario, but how can I read an object, like bar?

Thanks in advance.
