Parsing JSON to Excel using VBA - json

Question

I'm having some trouble with parsing JSON data in VBA. I have tried all of the examples online but I'm still unable to solve the issue. What I have managed to do is pull the JSON data into excel in the original format using another VBA code that pulled in data from another website. I've pasted the code that works below. It's not very clean and it has some duplication because I was just trying to see if I could pull the data.
All of the attempts I have tried to use VBA to parse the data have failed with a variety of errors depending on the approach I took. I'd be very grateful if someone could give me some advice on the simplest way to parse the data I've managed to pull. All I need is the data in columns which I can then use in other sheets in the worbook. I've attached a picture of the data that I've pulled. I have managed to parse JSON data from another webpage and in the code I included each column heading for the JSON data. For this new webpage, the JSON data is nested and there are loads of unique rows so I've not taken this approach. Many thanks

Here is VBA example showing how the JSON sample by the link can be converted to 2D array and output to worksheet. Import JSON.bas module into the VBA project for JSON processing.
Option Explicit
Sub Test()
Dim sJSONString As String
Dim vJSON
Dim sState As String
Dim aData()
Dim aHeader()
' Retrieve JSON content
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", "https://pastebin.com/raw/hA2UEDXy", True
.send
Do Until .readyState = 4: DoEvents: Loop
sJSONString = .responseText
End With
' Parse JSON sample
JSON.Parse sJSONString, vJSON, sState
If sState = "Error" Then MsgBox "Invalid JSON": End
' Convert JSON to 2D Array
JSON.ToArray vJSON("AppointmentList"), aData, aHeader
' Output to worksheet #1
Output aHeader, aData, ThisWorkbook.Sheets(1)
MsgBox "Completed"
End Sub
Sub Output(aHeader, aData, oDestWorksheet As Worksheet)
With oDestWorksheet
.Activate
.Cells.Delete
With .Cells(1, 1)
.Resize(1, UBound(aHeader) - LBound(aHeader) + 1).Value = aHeader
.Offset(1, 0).Resize( _
UBound(aData, 1) - LBound(aData, 1) + 1, _
UBound(aData, 2) - LBound(aData, 2) + 1 _
).Value = aData
End With
.Columns.AutoFit
End With
End Sub
The output for me is as follows (click to enlarge):
BTW, the similar approach applied in other answers.
