Parsing JSON

I'm struggling to parse and iterate over a JSON array of "key/object" elements. For instance, something in this format:

{
   "key1":{
      "param1":value,
      "param2":value
   },
   "key2":{
      "parm1":value,
      "param2":value
   }
}

{
   "key1":{
      "param1":value,
      "param2":value
   },
   "key2":{
      "parm1":value,
      "param2":value
   }
}

{
   "key1":{
      "param1":value,
      "param2":value
   },
   "key2":{
      "parm1":value,
      "param2":value
   }
}

{
   "key1":{
      "param1":value,
      "param2":value
   },
   "key2":{
      "parm1":value,
      "param2":value
   }
}
