                ]
            }]}

what is the easiest way to parse it into an array of json elements and use it for data binding

Answer 1

Using Json.Net

var array = Newtonsoft.Json.Linq.JArray.Parse(jsonString);

Using WinRT API's JsonArray class

var array = Windows.Data.Json.JsonArray.Parse(jsonString);

BTW, your JSON is invalid according to JSON Lint

According to me this is valid JSON array

[
    {
        "catlist": [
            {
                "area_id": "1",
                "area_name": "Ko",
                "categories": [
                    {
                        "cat_id": "1",
                        "cat_name": "Hot",
                        "chk_value": "2",
                        "sublist": [
                            {
                                "sub_id": "5",
                                "sub_name": "Beach"
                            },
                            {
                                "sub_id": "6",
                                "sub_name": "Beach"
                            },
                            {
                                "sub_id": "7",
                                "sub_name": "Beach"
                            }
                        ]
                    },
                    {
                        "cat_id": "2",
                        "cat_name": "Dining",
                        "chk_value": "1",
                        "sublist": [
                            {
                                "sub_id": "1",
                                "sub_name": "Road"
                            },
                            {
                                "sub_id": "2",
                                "sub_name": "Soi "
                            }
                        ]
                    }
                ]
            }
        ]
    }
]

If you want to deserialize the JSON, you should like this.

var Obj = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject[]>(jsonString);

public class Sublist
{
    public string sub_id { get; set; }
    public string sub_name { get; set; }
}

public class Category
{
    public string cat_id { get; set; }
    public string cat_name { get; set; }
    public string chk_value { get; set; }
    public List<Sublist> sublist { get; set; }
}

public class Catlist
{
    public string area_id { get; set; }
    public string area_name { get; set; }
    public List<Category> categories { get; set; }
}

public class RootObject
{
    public List<Catlist> catlist { get; set; }
}
