To fix the issue you can do I have a request.json in mootools to get some data from a php function returning the following: , You access the json data as a normal javascript object.
code :
onSuccess: function(jsonData){
    var container = document.id('container');
    var items = jsonData.listItems;
    Array.each(items, function(row){
        new Element('div').adopt(
            new Element('h1', {text:row.sessionName}),
            new Element('h2.count', {text:row.sessionCount})

wish helps you this is the full parsing of your JSON string you are getting form graph.facebook.com API :
code :
ArrayList<HashMap<String,String>> arrahaspmap=new 
HashMap<String,String> hashmaptemp;
JSONObject jsonObj;
 try {
    jsonObj = new JSONObject(sdskd);
    JSONArray jsonArr = jsonObj.getJSONArray("data");
    System.out.println("jsonArr jsonArr jsonArr jsonArr :: "+jsonArr.length());

    for(int i = 0; i < jsonArr .length(); i++)
           JSONObject jsonArrObj = jsonArr.getJSONObject(i);
           hashmaptemp=new HashMap<String, String>();
           hashmaptemp.put("id", jsonArrObj.getString("id"));
           hashmaptemp.put("end_time", jsonArrObj.getString("end_time"));
           hashmaptemp.put("location", jsonArrObj.getString("location"));
           hashmaptemp.put("name", jsonArrObj.getString("name"));
           hashmaptemp.put("rsvp_status", jsonArrObj.getString("rsvp_status"));
  JSONObject jsonobjpaging= jsonObj.getJSONObject("paging");
  String strprevious=jsonobjpaging.getString("previous");
  String strnext=jsonobjpaging.getString("next");
  System.out.println("jsonobjpaging previous :: "+strprevious);

  System.out.println("strnext next :: "+strnext);
} catch (JSONException e) {

How can I Read/Write array of objects from/to JSON using a Swift class that matches JSON from NewtonSoft (JSON.Net) comp

I hope this helps . I discovered the code I need to use in Swift which allows me to read and write the JSON (array of objects) that is output by JSON.Net.
I've added two methods to my SiteKey object :
code :
func loadJson(filename fileName: String) -> [SiteKey]
func writeJson(filename fileName: String, allSiteKeys : [SiteKey])
class SiteKey : Codable{
    var Key : String
    var MaxLength : Int
    var HasSpecialChars : Bool
    var HasUpperCase : Bool

    init(key : String, maxLength : Int,
         hasSpecialChars : Bool,
         hasUpperCase : Bool){
        Key = key;
        MaxLength = maxLength;
        HasSpecialChars = hasSpecialChars;
        HasUpperCase = hasUpperCase;

    func loadJson(filename fileName: String) -> [SiteKey]? {
        if let url = Bundle.main.url(forAuxiliaryExecutable: fileName) {
            do {
                let data = try Data(contentsOf: url)
                let decoder = JSONDecoder()
                let allKeys = try decoder.decode([SiteKey].self, from: data)
                return allKeys
            } catch {
        return nil

    func writeJson(filename fileName: String, allSiteKeys : [SiteKey]){
        let Data = try? JSONEncoder().encode(allSiteKeys)

            let pathAsURL = URL(fileURLWithPath: fileName)
            do {
                try Data?.write(to: pathAsURL)
            catch {
                print("Failed to write JSON data: \(error.localizedDescription)")
let newSiteKey = siteKey.loadJson(filename: "/Users/fakeUser/Documents/Dev/all.json")

JSON diff of large JSON data, finding some JSON as a subset of another JSON

By : Kiran Patil

I wish this helpful for you Beyond Compare works well, if you set up a JSON file format in it to use Python to pretty-print the JSON. Sample setup for Windows:
Install Python 2.7. In Beyond Compare, go under Tools, under File Formats. Click New. Choose Text Format. Enter "JSON" as a name. Under the General tab: Mask: *.json Under the Conversion tab: Conversion: External program (Unicode filenames) Loading: c:\Python27\python.exe -m json.tool %s %t Note, that second parameter in the command line must be %t, if you enter two %ss you will suffer data loss. Click Save.
