I have tried to parse the JSON string from Yahoo finance stock data from the below URL to CSV using various tools (JSON.NET, etc.,) available in internet.
MSFT Yahoo Data
I want to parse JSON string to CSV as below format.
Date | Open | High | Low | Close | Volume
Please any one help me to resolve this. Thanks in advance.
1) You need to define classes for Yahoo JSON schema: (Modified: Some values might be null. So, I have modified them as null-able variables)
public class Pre
{
public string timezone { get; set; }
public int end { get; set; }
public int start { get; set; }
public int gmtoffset { get; set; }
}
public class Regular
{
public string timezone { get; set; }
public int end { get; set; }
public int start { get; set; }
public int gmtoffset { get; set; }
}
public class Post
{
public string timezone { get; set; }
public int end { get; set; }
public int start { get; set; }
public int gmtoffset { get; set; }
}
public class CurrentTradingPeriod
{
public Pre pre { get; set; }
public Regular regular { get; set; }
public Post post { get; set; }
}
public class Meta
{
public string currency { get; set; }
public string symbol { get; set; }
public string exchangeName { get; set; }
public string instrumentType { get; set; }
public int firstTradeDate { get; set; }
public int gmtoffset { get; set; }
public string timezone { get; set; }
public string exchangeTimezoneName { get; set; }
public CurrentTradingPeriod currentTradingPeriod { get; set; }
public string dataGranularity { get; set; }
public List<string> validRanges { get; set; }
}
public class Quote
{
public List<object> volume { get; set; }
public List<double?> low { get; set; }
public List<double?> high { get; set; }
public List<double?> close { get; set; }
public List<double?> open { get; set; }
}
public class Unadjclose
{
public List<double?> unadjclose { get; set; }
}
public class Unadjquote
{
public List<double?> unadjopen { get; set; }
public List<double?> unadjclose { get; set; }
public List<double?> unadjhigh { get; set; }
public List<double?> unadjlow { get; set; }
}
public class Indicators
{
public List<Quote> quote { get; set; }
public List<Unadjclose> unadjclose { get; set; }
public List<Unadjquote> unadjquote { get; set; }
}
public class Result
{
public Meta meta { get; set; }
public List<int> timestamp { get; set; }
public Indicators indicators { get; set; }
}
public class Chart
{
public List<Result> result { get; set; }
public object error { get; set; }
}
public class RootObject
{
public Chart chart { get; set; }
}
2) You need to deserialize JSON into object
var str = wc.DownloadString("https://query1.finance.yahoo.com/v7/finance/chart/MSFT?range=25y&interval=1d&indicators=quote&includeTimestamps=true&includePrePost=false&corsDomain=finance.yahoo.com");
var data = JsonConvert.DeserializeObject<Rootobject>(str);
3) Then, iterate through this object and build your CSV. Working sample: (Modified: Some values might be null. So, I have modified the code to check if that null-able variables preserves value using HasValue property before converting to string)
var wc = new WebClient();
var str = wc.DownloadString("https://query1.finance.yahoo.com/v7/finance/chart/MSFT?range=25y&interval=1d&indicators=quote&includeTimestamps=true&includePrePost=false&corsDomain=finance.yahoo.com");
var data = JsonConvert.DeserializeObject<Rootobject>(str);
var result = new List<string>();
var quotesInfo = data.chart.result.First();
for (var i = 0; i < quotesInfo.timestamp.Count; i++)
{
var quotesStr = new List<string>();
var quoteData = quotesInfo.indicators.quote.First();
quotesStr.Add(UnixTimeStampToDateTime(quotesInfo.timestamp[i]).ToString(CultureInfo.InvariantCulture));
quotesStr.Add(quoteData.open[i].HasValue ? quoteData.open[i].ToString() : string.Empty);
quotesStr.Add(quoteData.high[i].HasValue ? quoteData.high[i].ToString() : string.Empty);
quotesStr.Add(quoteData.low[i].HasValue ? quoteData.low[i].ToString() : string.Empty);
quotesStr.Add(quoteData.close[i].HasValue ? quoteData.close[i].ToString() : string.Empty);
quotesStr.Add(quoteData.volume[i] != null ? quoteData.volume[i].ToString() : string.Empty);
result.Add(string.Join(",", quotesStr));
}
File.WriteAllLines("result.csv",result);
Modified: And, I have added the code to convert the timestamp to DateTime format.
public static DateTime UnixTimeStampToDateTime(double unixTimeStamp)
{
var dtDateTime = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
dtDateTime = dtDateTime.AddSeconds(unixTimeStamp).ToUniversalTime();
return dtDateTime;
}
At the end you will receive comma delimeted CSV file

I've been searching around for a long while for this, I haven't found any solutions to my issue which is:
I've been trying get a json data individually from a whole source seen here:
{"TargetId":0,"ProductType":null,"AssetId":1239281845,"ProductId":0,"Name":"❤️🍀𝐒𝐀𝐋𝐄❗️🍀❤️ Red&Black Flannel + Backpack","Description":"Shirt Image","AssetTypeId":1,"Creator":{"Id":124026176,"Name":"TheDestroyerPeter","CreatorType":"User","CreatorTargetId":124026176},"IconImageAssetId":0,"Created":"2017-12-12T19:48:24.693Z","Updated":"2017-12-12T19:48:24.693Z","PriceInRobux":null,"PriceInTickets":null,"Sales":0,"IsNew":false,"IsForSale":false,"IsPublicDomain":false,"IsLimited":false,"IsLimitedUnique":false,"Remaining":null,"MinimumMembershipLevel":0,"ContentRatingTypeId":0}
now what I've been trying to do with it is get the Product Name using C# and the product name is "❤️🍀𝐒𝐀𝐋𝐄❗️🍀❤️ Red&Black Flannel + Backpack", my issue is that I haven't found a way to extract the data, and when I have I haven't been able to get the right data, because instead if gives me "TheDestroyerPeter"
I've written up code, and deleted it, it was really sloppy and it would take awhile to rewrite, I appreciate any solutions
-whoever I am
You can use JavaScriptSerializer class, which is part of the System.Web.Script namespace.
For example :
var jsonString = #"{""name"":""John Doe"",""age"":20}";
var JSONObj = new JavaScriptSerializer().Deserialize<Dictionary<string, string>>(jsonString );
and then JSONObj["name"]; gives you "John Doe"
in this case you can use it :
public class Creator
{
public int Id { get; set; }
public string Name { get; set; }
public string CreatorType { get; set; }
public int CreatorTargetId { get; set; }
}
public class RootObject
{
public int TargetId { get; set; }
public object ProductType { get; set; }
public int AssetId { get; set; }
public int ProductId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public int AssetTypeId { get; set; }
public Creator Creator { get; set; }
public int IconImageAssetId { get; set; }
public DateTime Created { get; set; }
public DateTime Updated { get; set; }
public object PriceInRobux { get; set; }
public object PriceInTickets { get; set; }
public int Sales { get; set; }
public bool IsNew { get; set; }
public bool IsForSale { get; set; }
public bool IsPublicDomain { get; set; }
public bool IsLimited { get; set; }
public bool IsLimitedUnique { get; set; }
public object Remaining { get; set; }
public int MinimumMembershipLevel { get; set; }
public int ContentRatingTypeId { get; set; }
}
use Newtonsoft.Json
var jsonString = #"{""TargetId"":0,""ProductType"":null,""AssetId"":1239281845,""ProductId"":0,""Name"":""❤️🍀𝐒𝐀𝐋𝐄❗️🍀❤️ Red&Black Flannel + Backpack"",""Description"":""Shirt Image"",""AssetTypeId"":1,""Creator"":{""Id"":124026176,""Name"":""TheDestroyerPeter"",""CreatorType"":""User"",""CreatorTargetId"":124026176},""IconImageAssetId"":0,""Created"":""2017-12-12T19:48:24.693Z"",""Updated"":""2017-12-12T19:48:24.693Z"",""PriceInRobux"":null,""PriceInTickets"":null,""Sales"":0,""IsNew"":false,""IsForSale"":false,""IsPublicDomain"":false,""IsLimited"":false,""IsLimitedUnique"":false,""Remaining"":null,""MinimumMembershipLevel"":0,""ContentRatingTypeId"":0}";
var obj = JsonConvert.DeserializeObject<RootObject>(jsonString);
Console.WriteLine(obj.Creator.Name); //"TheDestroyerPeter"
been a while since I posted here. I'm working on an app and need to fetch statistics for a particular video using JSON (C#, UWP).
I already have the statistics as a JSON string but can't seem to parse them properly using Newtonsoft. The value always comes back null. This is my code:
var url = "https://www.googleapis.com/youtube/v3/videos?id=" + videoId + "&key=" + cl.googleAPIKey + "&part=snippet,contentDetails,statistics,status";
var http = new HttpClient();
var response = await http.GetStringAsync(url);
var statistics = JsonConvert.DeserializeObject<Statistics>(response);
string totalViews = statistics.viewCount;
The classes generated by Json2CSharp are:
public class PageInfo
{
public int totalResults { get; set; }
public int resultsPerPage { get; set; }
}
public class Default
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Medium
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class High
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Standard
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Maxres
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Thumbnails
{
public Default #default { get; set; }
public Medium medium { get; set; }
public High high { get; set; }
public Standard standard { get; set; }
public Maxres maxres { get; set; }
}
public class Localized
{
public string title { get; set; }
public string description { get; set; }
}
public class Snippet
{
public DateTime publishedAt { get; set; }
public string channelId { get; set; }
public string title { get; set; }
public string description { get; set; }
public Thumbnails thumbnails { get; set; }
public string channelTitle { get; set; }
public List<string> tags { get; set; }
public string categoryId { get; set; }
public string liveBroadcastContent { get; set; }
public Localized localized { get; set; }
}
public class ContentDetails
{
public string duration { get; set; }
public string dimension { get; set; }
public string definition { get; set; }
public string caption { get; set; }
public bool licensedContent { get; set; }
public string projection { get; set; }
}
public class Status
{
public string uploadStatus { get; set; }
public string privacyStatus { get; set; }
public string license { get; set; }
public bool embeddable { get; set; }
public bool publicStatsViewable { get; set; }
}
public class Statistics
{
public string viewCount { get; set; }
public string likeCount { get; set; }
public string dislikeCount { get; set; }
public string favoriteCount { get; set; }
public string commentCount { get; set; }
}
public class Item
{
public string kind { get; set; }
public string etag { get; set; }
public string id { get; set; }
public Snippet snippet { get; set; }
public ContentDetails contentDetails { get; set; }
public Status status { get; set; }
public Statistics statistics { get; set; }
}
public class RootObject
{
public string kind { get; set; }
public string etag { get; set; }
public PageInfo pageInfo { get; set; }
public List<Item> items { get; set; }
}
As I say the value will always come back as null regardless of the video ID.
Does anyone have any ideas?
Thanks
You are deserializing to the wrong class. Json2Csharp generated many classes, but Statistics is way down the tree. You should deserialize the RootObject instead:
var root = JsonConvert.DeserializeObject<RootObject>( response );
And then navigate to the statistics within the resulting class structure like for example:
foreach ( var statistics in root.Items.Select( i => i.Statistics) )
{
//do something
}
I am trying to deserialize my json code. The json code is in a string, and the json code looks like this (so I'm assuming it's json objects)
{
"post_id":13,
"thread_id":9,
"user_id":1,
"username":"Username",
"post_date":1496439611,
"message":"testzilla - 2133746943A9",
"ip_id":698,
"message_state":"visible",
"attach_count":0,
"position":0,
"likes":0,
"like_users":"a:0:{}",
"warning_id":0,
"warning_message":"",
"last_edit_date":1496476199,
"last_edit_user_id":0,
"edit_count":9,
"node_id":34,
"title":"Test",
"tags":"a:0:{}",
"node_title":"test node",
"node_name":null,
"message_html":"testzilla - 2133746943A9",
"absolute_url":"url"
}
How would I put the "message" container inside a string? So that the string would contain "testzilla - 2133746943A9" without the quotation marks. I am using JSON.Net
The name of the string that contains this json code is "MACs". Thanks in advance. PS: I am a new coder.
there is a missing "{" at the beginning of your json file, try adding it
You need to create your c# class to deserialize your json string. As per your json structure i have created your class given below
public class MyClass
{
public int post_id { get; set; }
public int thread_id { get; set; }
public int user_id { get; set; }
public string username { get; set; }
public int post_date { get; set; }
public string message { get; set; }
public int ip_id { get; set; }
public string message_state { get; set; }
public int attach_count { get; set; }
public int position { get; set; }
public int likes { get; set; }
public string like_users { get; set; }
public int warning_id { get; set; }
public string warning_message { get; set; }
public int last_edit_date { get; set; }
public int last_edit_user_id { get; set; }
public int edit_count { get; set; }
public int node_id { get; set; }
public string title { get; set; }
public string tags { get; set; }
public string node_title { get; set; }
public object node_name { get; set; }
public string message_html { get; set; }
public string absolute_url { get; set; }
}
No need to use library JSON.Net. You can do this by simply using System.Web.Script.Serialization to deserialize the json string.
Note : System.Web.Script.Serialization is available inside System.Web.Extensions namespace.
Below is the complete code. I kept your json data inside a file named as "test2.json" and consuming it from that file.
using System;
using System.Web.Script.Serialization;
using System.IO;
namespace DesrializeJson1ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var jsonFile = "test2.json";
string jsonstring = File.ReadAllText(jsonFile);
var serializer = new JavaScriptSerializer();
MyClass aClass = serializer.Deserialize<MyClass>(jsonstring);
Console.WriteLine("--------------------------");
Console.WriteLine("message :" + aClass.message);
Console.WriteLine("message_state :" + aClass.message_state);
Console.WriteLine("warning_message :" + aClass.warning_message);
Console.WriteLine("message_html :" + aClass.message_html);
Console.WriteLine("--------------------------");
Console.Read();
}
}
public class MyClass
{
public int post_id { get; set; }
public int thread_id { get; set; }
public int user_id { get; set; }
public string username { get; set; }
public int post_date { get; set; }
public string message { get; set; }
public int ip_id { get; set; }
public string message_state { get; set; }
public int attach_count { get; set; }
public int position { get; set; }
public int likes { get; set; }
public string like_users { get; set; }
public int warning_id { get; set; }
public string warning_message { get; set; }
public int last_edit_date { get; set; }
public int last_edit_user_id { get; set; }
public int edit_count { get; set; }
public int node_id { get; set; }
public string title { get; set; }
public string tags { get; set; }
public string node_title { get; set; }
public object node_name { get; set; }
public string message_html { get; set; }
public string absolute_url { get; set; }
}
}
OUTPUT
You can use regex to get the value you want.
string yourJsonString = #"{ ""post_id"":13, ""thread_id"":9, ""user_id"":1, ""username"":""Username"", ""post_date"":1496439611, ""message"":""testzilla - 2133746943A9"", ""ip_id"":698, ""message_state"":""visible"", ""attach_count"":0, ""position"":0, ""likes"":0, ""like_users"":""a:0:{}"", ""warning_id"":0, ""warning_message"":"""", ""last_edit_date"":1496476199, ""last_edit_user_id"":0, ""edit_count"":9, ""node_id"":34, ""title"":""Test"", ""tags"":""a:0:{}"", ""node_title"":""test node"", ""node_name"":null, ""message_html"":""testzilla - 2133746943A9"", ""absolute_url"":""url""}";
string value = System.Text.RegularExpressions.Regex.Match(yourJsonString,#"""message"":(.+?),").Groups[1].Value.Replace(#"""","");
MessageBox.Show(value);
You can also use dynamic type for deserialization. You will no need to write object for deserialization:
var str = "{\r\n \"post_id\":13,\r\n \"thread_id\":9,\r\n \"user_id\":1,\r\n \"username\":\"Username\",\r\n \"post_date\":1496439611,\r\n \"message\":\"testzilla - 2133746943A9\",\r\n \"ip_id\":698,\r\n \"message_state\":\"visible\",\r\n \"attach_count\":0,\r\n \"position\":0,\r\n \"likes\":0,\r\n \"like_users\":\"a:0:{}\",\r\n \"warning_id\":0,\r\n \"warning_message\":\"\",\r\n \"last_edit_date\":1496476199,\r\n \"last_edit_user_id\":0,\r\n \"edit_count\":9,\r\n \"node_id\":34,\r\n \"title\":\"Test\",\r\n \"tags\":\"a:0:{}\",\r\n \"node_title\":\"test node\",\r\n \"node_name\":null,\r\n \"message_html\":\"testzilla - 2133746943A9\",\r\n \"absolute_url\":\"url\"\r\n}";
dynamic obj = JsonConvert.DeserializeObject(str);
var postId = obj.post_id;
Console.WriteLine("postId:" + postId);
output:
postId:13
Im new in developing windows phone app --> i have problem so i have tried all the possible solutions but with no vain:-
the application tried to take result from webservice the result come back like this:-

Please help me to parse all of the json result (locally i mean without conection to web)and what is the code to do that.
thank you all
First, your JSON is all a string property of "D". You can't deserialize it to RootClass. Second, your JSON contains invalid escape characters in the LastTickTime area. I removed both of these, and the JSON parses without errors of any kind. I just used a console app to test it.

Console.WriteLine(foo.UserId); // Writes 579
UPDATE
If you have no control over what you get back, do the following:
Take the response and get rid of the / combination. As such:
string webResponse = "your long web response from the server";
webResponse = webResponse.Replace(#"\/", "/");
// If dynamic isn't in the phone subset, you'll need a class here containing "d" as a string.
var jsonOuter = JsonConvert.DeserializeObject<dynamic>(webResponse);
var jsonInner = JsonConvert.DeserializeObject<RootObject>(jsonOuter.d);
if (jsonInner.UserId > .....)
I am trying to create a list of customer names that is fetched from a Json call but I get an error:
cannot implicitly convert type System.Collections.Generic.List<char>
to System.Collections.Generic.List<string>
I am using these 2 classes:
Customers:
namespace eko_app
{
static class Customers
{
public static List<CustomerResponse> GetCustomers(string customerURL)
{
List<CustomerResponse> customers = new List<CustomerResponse>();
try
{
var w = new WebClient();
var jsonData = string.Empty;
// make the select products call
jsonData = w.DownloadString(customerURL);
if (!string.IsNullOrEmpty(jsonData))
{
// deserialize the json to c# .net
var response = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(jsonData);
if (response != null)
{
customers = response.response;
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
return customers;

HomeForm:
private void GetCustomerNameList()
{
// get customers
customerURL = "https://eko-app.com/BusinessAssociate/list_associates/1/sessionId:" + sessionID + ".json";
var customers = Customers.GetCustomers(customerURL);
List<string> customerNames = new List<string>();
foreach (var c in customers)
{
customerNames = c.BusinessAssociate.name.ToList(); <--------error thrown here
}
}
The error is thrown at customerNames = c.BusinessAssociate.name.ToList(); on the HomeForm.
What am I doing wrong in creating a list of customer names?
I think you wanted to add all Customer.BusinessAssociate names to list:
foreach (var c in customers)
{
customerNames.Add(c.BusinessAssociate.name);
}
What you originally written converted each name string to char list.
You're assigning a list of chars (string) into a list of strings.
Try something like this outside of the foreach loop:
customerNames = customers.Select(x => x.BusinessAssociate.name).ToList();
This also makes the initialization of cutomerNames redundant.
Instead of foreach use:
customerNames = customers.Select(c => c.BusinessAssociate.name).ToList();
