Answer 1

Take a look at the below example. 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()
    Dim vResult

    ' Retrieve question #50068973 HTML content
    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "https://stackoverflow.com/questions/50068973", False
        .send
        sJSONString = .responseText
    End With
    ' Extract JSON sample from the question
    sJSONString = "{" & Split(sJSONString, "<code>{", 2)(1)
    sJSONString = Split(sJSONString, "</code>", 2)(0)
    ' Parse JSON sample
    JSON.Parse sJSONString, vJSON, sState
    If sState = "Error" Then
        MsgBox "Invalid JSON"
        End
    End If
    ' Convert raw JSON to array and output to worksheet #1
    JSON.ToArray vJSON, aData, aHeader
    With Sheets(1)
        .Cells.Delete
        .Cells.WrapText = False
        OutputArray .Cells(1, 1), aHeader
        Output2DArray .Cells(2, 1), aData
        .Columns.AutoFit
    End With
    ' Flatten JSON
    JSON.Flatten vJSON, vResult
    ' Convert flattened JSON to array and output to worksheet #2
    JSON.ToArray vResult, aData, aHeader
    With Sheets(2)
        .Cells.Delete
        .Cells.WrapText = False
        OutputArray .Cells(1, 1), aHeader
        Output2DArray .Cells(2, 1), aData
        .Columns.AutoFit
    End With
    MsgBox "Completed"

End Sub

Sub OutputArray(oDstRng As Range, aCells As Variant)

    With oDstRng
        .Parent.Select
        With .Resize(1, UBound(aCells) - LBound(aCells) + 1)
            .NumberFormat = "@"
            .Value = aCells
        End With
    End With

End Sub

Sub Output2DArray(oDstRng As Range, aCells As Variant)

    With oDstRng
        .Parent.Select
        With .Resize( _
                UBound(aCells, 1) - LBound(aCells, 1) + 1, _
                UBound(aCells, 2) - LBound(aCells, 2) + 1)
            .NumberFormat = "@"
            .Value = aCells
        End With
    End With

End Sub

The output on the worksheet #1 for the raw sample you provided is as follows:

And there is the flattened sample output on the worksheet #2:

BTW, the similar approach applied in other answers.
