This is json code (https://textsaver.flap.tv/lists/3ic4)
and i am trying
Sub test()
Dim req As New MSXML2.XMLHTTP60
Dim URL As String, ws As Worksheet
Dim json As Object, r, r1 As String
URL = "https://www.nseindia.com/api/quote-equity?symbol=DIVISLAB"
With req
.Open "GET", URL, False
.send
Set json = JsonConverter.ParseJson(.responseText)
r = json("data")(1)("CH_OPENING_PRICE")
r1 = json("data")(1)("CH_CLOSING_PRICE")
End With
Debug.Print r
Debug.Print r1
End Sub
I want to print TEXT underbelow mentioned point. its in picture also highlighted in blue.
json>[data]>{1}>CH_OPENING_PRICE & CH_CLOSING_PRICE.
It will be more helpful if anyone suggest me any website or book for basic idea about trim text from nested json.
First of all put json("data") in a variable:
set data = json("data")
'maybe you don't need the "set" keyword there, check documentation to your json library
Then iterate the data
For Each dataitem In data
r = dataitem("CH_OPENING_PRICE")
r1 = dataitem ("CH_CLOSING_PRICE")
Debug.Print r
Debug.Print r1
Next

I am trying to pull JSON values from a URL that I am working with at the moment. I may have done something like this before but I dont know what I'm missing here.
Here is the URL - https://eu-offering.kambicdn.org/offering/v2018/888/listView/golf.json?lang=en_GB&market=GB&client_id=2&channel_id=1&ncid=1568916879040&useCombined=true
And an image for clarity of what is needed to be extracted.
I ran a test using Tinman's approach as can be found here - How to get, JSON values to Work in VBA-JSON? , but i can't even apply his function, PrintJSONAccessors(), here
Public Sub exceljson()
Dim http As Object
Set http = CreateObject("MSXML2.XMLHTTP")
http.Open "GET",
"https://eu-offering.kambicdn.org/offering/v2018/888/listView/golf.json?lang=en_GB&market=GB&client_id=2&channel_id=1&ncid=1568916879040&useCombined=true", False
http.Send
Dim results As Variant
results = BitfinexTextToArray(http.responseText)
Worksheets(1).Range("A1").Resize(UBound(results), UBound(results,2)).Value = results
MsgBox ("complete")
End Sub
Function BitfinexTextToArray(responseText As String) As Variant
Dim item As Variant, JSON As Object
Dim MaxColumns As Long
Set JSON = ParseJson(responseText)
For Each item In JSON
If item.Count > MaxColumns Then MaxColumns = item.Count
Next
Dim results As Variant
ReDim results(1 To JSON.Count, 1 To MaxColumns)
Dim c As Long, r As Long
For Each item In JSON
r = r + 1
For c = 1 To item.Count
results(r, c) = item(c)
Next
Next
BitfinexTextToArray = results
End Function
I need help with pulling the following item values from each of the JSON "event"
1. "englishName"
2. "participant"
3. "oddsFractional"
NOTE: my example uses the JsonConverter library and requires you to add a reference to the Microsoft Scripting Runtime to access the Dictionary object.
I set up a test file with JSON loaded from your URL above. After parsing the JSON data, the exercise becomes understanding how the various levels are nested and what type of data structure is being used. In your JSON, it's a mix of Collection, Array, and Dictionary in various combinations. My example below shows how you have to stack up these nested references to get the data you're looking for.
Review the information in this answer to understand how the JSON is parsed into a hierarchical data structure.
Option Explicit
Public Sub test()
Dim fileNum As Long
fileNum = FreeFile()
Dim filename As String
filename = "C:\Temp\testdata.json"
Dim jsonInput As String
Open filename For Input As #fileNum
jsonInput = Input$(LOF(fileNum), fileNum)
Close fileNum
Dim json As Object
Set json = ParseJson(jsonInput)
Debug.Print " English Name = " & json("events")(1)("event")("englishName")
Debug.Print " Participant = " & json("events")(1)("betOffers")(1)("outcomes")(2)("participant")
Debug.Print "Odds Fractional = " & json("events")(1)("betOffers")(1)("outcomes")(2)("oddsFractional")
End Sub
An even better solution will be to create an intermediate variable and then loop over the contents in an array (or collection or dictionary).
I have started creating an excel for stock watch in 2010 and havent been able to parse properly.
Instead of getting the columns with [symbol] and prices i only get first four tags and nothing inside data.
This is the code:
Sub getJSON()
Set MyRequest = CreateObject("WinHttp.WinHttpRequest.5.1")
MyRequest.Open "GET", "https://www.nseindia.com/live_market/dynaContent/live_watch/stock_watch/foSecStockWatch.json"
MyRequest.Send
MsgBox MyRequest.ResponseText
Dim jsonText As String
Dim jsonObj As Dictionary
Dim jsonRows As Collection
Dim jsonRow As Collection
Dim ws As Worksheet
Dim currentRow As Long
Dim startColumn As Long
Dim i As Long
Set ws = Worksheets("Sheet1")
ws.Range("A1") = MyRequest.ResponseText
MsgBox ws.Range("A1").Value
jsonText = ws.Range("A1").Value
'jsonText = MyRequest.ResponseText
'Parse it
Set jsonObj = JSON.parse(jsonText)
'Get the rows collection
'Error here'
Set jsonRows = jsonObj("symbol")
'Set the starting row where to put the values
currentRow = 1
'First column where to put the values
startColumn = 2 'B
'Loop through all the values received
For Each jsonRow In jsonRows
'Now loop through all the items in this row
For i = 1 To jsonRow.Count
ws.Cells(currentRow, startColumn + i - 1).Value = jsonRow(i)
Next i
'Increment the row to the next one
currentRow = currentRow + 1
Next jsonRow
End Sub
Also as this is excel 2010 and doing it as a newbie let me know if this is the correct way to parse json as i am going to create multiple excels with different urls.
You need to inspect the JSON structure and write your code accordingly. The [] means collection which you can For Each over the items of. The {} means dictionary which you can loop over the keys of. The blue and green squares (in the image of your JSON below) are string literals (key,value pairs).
You initially get back a dictionary containing a mixture of key, value pairs (e.g. noChg, 5); with one key, data, being to a collection of inner dictionaries.
jsonObj("symbol") if you had parsed with ParseJson and following syntax:
Set jsonObj = JsonConverter.ParseJson(.responseText) '<== dictionary
would have failed as symbol is a key in the inner dictionaries, within the collection data, and not directly accessible from the initial top level JSON dictionary.
Instead, you need to loop the initial dictionary and write out the key, value pairs and test if the key is data. If the key is data, you instead need to loop the items in the collection (each being a dictionary), and loop the keys of those dictionaries.
A little thought as to how you increment row and column counters, and testing for the first time the inner dictionary keys are looped, to get the headers only once, will result in a tidy write out of data to sheet.
NOTE: I am using JSONConverter.bas to parse the JSON. After adding this to the project, I also go to VBE > Tools > References and add a reference to Microsoft Scripting Runtime.
VBA:
Option Explicit
Public Sub GetInfo()
Dim json As Object, item As Object, key As Variant, key2 As Variant, ws As Worksheet
Set ws = ThisWorkbook.Worksheets("Sheet1")
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", "https://www.nseindia.com/live_market/dynaContent/live_watch/stock_watch/foSecStockWatch.json", False
.setRequestHeader "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"
.send
Set json = JsonConverter.ParseJson(.responseText) '<== dictionary
End With
Dim r As Long, c As Long, headerRow As Long
For Each key In json '<== Loop initial dictionary
r = r + 1
If key = "data" Then '<==collection of dictionaries
For Each item In json("data")
headerRow = headerRow + 1
c = 1
For Each key2 In item '<== individual dictionary
If headerRow = 1 Then '<== test to write out headers of symbols info only once
ws.Cells(r, c) = key2
ws.Cells(r + 1, c) = item(key2)
Else
ws.Cells(r + 1, c) = item(key2)
End If
c = c + 1
Next
r = r + 1
Next
Else 'string literal key, value pairs
ws.Cells(r, 1) = key: ws.Cells(r, 2) = json(key)
End If
Next
End Sub
Sample of data in sheet:
I make a request to a website and paste the JSON response into a single cell.
I get an object required 424 error.
Sub GetJSON()
Dim hReq As Object
Dim JSON As Dictionary
Dim var As Variant
Dim ws As Worksheet
Set ws = Title
'create our URL string and pass the user entered information to it
Dim strUrl As String
strUrl = Range("M24").Value
Set hReq = CreateObject("MSXML2.XMLHTTP")
With hReq
.Open "GET", strUrl, False
.Send
End With
'wrap the response in a JSON root tag "data" to count returned objects
Dim response As String
response = "{""data"":" & hReq.responseText & "}"
Set JSON = JsonConverter.ParseJson(response)
'set array size to accept all returned objects
ReDim var(JSON("data").Count, 1)
Cells(25, 13) = JSON
Erase var
Set var = Nothing
Set hReq = Nothing
Set JSON = Nothing
End Sub
The URL that gives me the response in cell "M24":
https://earthquake.usgs.gov/ws/designmaps/asce7-10.json?latitude=36.497452&longitude=-86.949479&riskCategory=III&siteClass=C&title=Seismic
The code after Qharr's response. I get a run time 0 error even though the error says it ran successfully. Nothing is copied to my cells.
Public Sub GetInfo()
Dim URL As String, json As Object
Dim dict As Object
URL = "https://earthquake.usgs.gov/ws/designmaps/asce7-10.json?latitude=36.497452&longitude=-86.949479&riskCategory=III&siteClass=C&title=Seismic"
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", URL, False
.Send
Set json = JsonConverter.ParseJson(.responseText) '<== dictionary
ThisWorkbook.Worksheets("Title").Cells(1, 1) = .responseText
Set dict = json("response")("data")
ws.Cells(13, 27) = "ss: " & dict("ss") & Chr$(10) & "s1: " & dict("s1")
End With
End Sub
I'm not clear what you mean. The entire response can go in a cell as follows.
JSON is an object so you would need Set keyword but you can't set a cell range to the dictionary object - the source of your error.
Option Explicit
Public Sub GetInfo()
Dim URL As String, json As Object
URL = "https://earthquake.usgs.gov/ws/designmaps/asce7-10.json?latitude=36.497452&longitude=-86.949479&riskCategory=III&siteClass=C&title=Seismic"
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", URL, False
.send
Set json = JsonConverter.ParseJson(.responseText) '<== dictionary
ThisWorkbook.Worksheets("Sheet1").Cells(1, 1) = .responseText
End With
End Sub
When you use parsejson you are converting to a dictionary object which you need to do something with. There is simply too much data nested inside to write anything readable (if limit not exceeded) into one cell.
Inner dictionary data quickly descends into nested collections. The nested collection count comes from
Dim dict As Object
Set dict = json("response")("data")
Debug.Print "nested collection count = " & dict("sdSpectrum").Count + dict("smSpectrum").Count
To get just s1 and ss values parse them out:
Dim dict As Object
Set dict = json("response")("data")
ws.Cells(1, 2) = "ss: " & dict("ss") & Chr$(10) & "s1: " & dict("s1")
I have figured out the solution to pasting the response text with Excel 2003. Below is my finished code.
Public Sub datagrab()
Dim URL As String
Dim ws As Object
Dim xmlhttp As New MSXML2.XMLHTTP60
URL = Range("M24").Value 'This is the URL I'm requesting from
xmlhttp.Open "GET", URL, False
xmlhttp.Send
Worksheets("Title").Range("M25").Value = xmlhttp.responseText
End Sub
Can someone with experience using JSON and Access together tell me what I'm doing wrong with this code? I'm trying to parse a JSON file and there's one nested data item that I can't seem to extract. The problem portion of the JSON data is as follows:
credits":{
"director":[{"displayName":"Bradley Cooper","firstName":"Bradley","lastName":"Cooper","bio":""}],
"cast":["Bradley Cooper"," Lady Gaga"," Andrew Dice Clay"," Dave Chappelle"," Sam Elliott"]
}
I can extract the cast names with no problem, but I can't retrieve the "displayname" for the director. The nested "{}" brackets inside the "director" item are throwing me off. Here's my code:
Sub JSON_prob_demo()
Dim url As String, data As String
Dim xml As Object, JSON As Object, colObj As Object, colobj2 As Object, colObj3 As Object, item As Object
Dim c1 As Variant, varX As Variant
url = "https://www.tiff.net/data/films/a-star-is-born.json"
Set xml = CreateObject("MSXML2.XMLHTTP")
With xml
.Open "GET", url, False
.send
data = .responseText
End With
Set JSON = JsonConverter.ParseJson(data)
Set colObj = JSON("credits")
For Each c1 In colObj("cast")
Debug.Print c1
Next
Debug.Print "Director:"
Set colobj2 = colObj("director")
For Each c1 In colobj2
Debug.Print c1("displayname")
Next
End Sub
I've been able to extract the names of the four director fields, but I simply cannot access their values. What's the trick?
Try this
Sub getHTTP()
Dim Url As String, data As String
Dim xml As Object, JSON As Object, colObj, item
Url = "https://www.tiff.net/data/films/a-star-is-born.json"
Set xml = CreateObject("MSXML2.ServerXMLHTTP")
With xml
.Open "GET", Url, False
.send
data = .responseText
End With
Set JSON = JsonConverter.ParseJson(data)
Set colObj = JSON("credits")("director")
For Each item In colObj
For j = 0 To item.Count - 1
Debug.Print item.Items()(j)
Next
Next
End Sub
Print
Note: Item is dictionary object so used Debug.Print item.Items()(j) to retrieve key values.
I'm trying to access in VBA to over 508 "tank_id"s from a JSON file as you can see here.
I'm using cStringBuilder, cJSONScript and JSONConverter to parse the JSON file.
My main issue is that I can't pass threw all those ids because I don't know how to get the "1" "33" "49" "81" that are without names.
Here si the code I tried to get them, without success.
Const myurl2 As String = "https://api.worldoftanks.eu/wot/encyclopedia/vehicles/?application_id=demo&fields=tank_id"
Sub List_id_vehicules()
Dim strRequest
Dim xmlHttp: Set xmlHttp = CreateObject("msxml2.xmlhttp")
Dim response As Object
Dim rows As Integer
Dim counter As Integer
Dim j As String
Dim k As Integer: k = 2
Dim url As String
url = myurl2
xmlHttp.Open "GET", url, False
xmlHttp.setRequestHeader "Content-Type", "text/xml"
xmlHttp.send
While Not xmlHttp.Status = 200 '<---------- wait
Wend
Set response = ParseJson(xmlHttp.ResponseText)
rows = response("meta")("count")
For counter = 1 To rows
j = counter
Dim yop As String
yop = "data[" & j & "][" & j & "]"
Sheets(2).Cells(1 + counter, 1).Value = response('data[counter]')['tank_id']
Next counter
END Sub
Could someone help me ?
The JSONConverter essentially parses the JSON text string into a set of nested Dictionary objects. So when the ParseJson function returns an Object, it's really a Dictionary. Then, when you access response("meta"), the "meta" part is the Key to the Dictionary object. It's the same thing as you nest down through the JSON.
So when you try to access response("data")("3137"), you're accessing the Dictionary returned by response("data") with the key="3137". Now the trick becomes how to get all the Keys from the response("data") object.
Here's a sample bit of code to illustrate how you can list all the tank IDs in the JSON data section:
Option Explicit
Sub ListVehicleIDs()
Const jsonFilename As String = "C:\Temp\tanks.json"
Dim fileHandle As Integer
Dim jsonString As String
fileHandle = FreeFile
Open jsonFilename For Input As #fileHandle
jsonString = Input$(LOF(fileHandle), #fileHandle)
Close #fileHandle
Dim jsonObj As Object
Set jsonObj = ParseJson(jsonString)
Dim tankCount As Long
tankCount = jsonObj("meta")("count")
Dim tankIDs As Dictionary
Set tankIDs = jsonObj("data")
Dim tankID As Variant
For Each tankID In tankIDs.keys
Debug.Print "Tank ID = " & tankID
Next tankID
End Sub
