for your example     profiles      name   john    age   44     name   Alex   age  11      you will have to do something of this effect   JSONObject myjson   new JSONObject the json   JSONArray the json array   myjson getJSONArray  profiles      this returns the array object   Then iterating will be as follows       int size   the json array length        ArrayList lt JSONObject gt  arrays   new ArrayList lt JSONObject gt         for  int i   0  i  lt  size  i              JSONObject another json object   the json array getJSONObject i                 Blah blah blah                arrays add another json object            Finally JSONObject   jsons   new JSONObject arrays size     arrays toArray jsons      The end      You will have to determine if the data is an array  simply checking that charAt 0  starts with   character    Hope this helps
