(Excel) JSON: Nested Array

Here we have a JSON object that contains nested arrays. This example demonstrates how to access the contents of the nested arrays.

{
 "numbers" : [ 
    ["even", 2, 4, 6, 8], 
    ["prime", 2, 3, 5, 7, 11, 13] 
  ] }

Dim json As Chilkat.JsonObject
Set json = Chilkat.NewJsonObject

' This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars).
' The presence of whitespace chars for pretty-printing makes no difference to the Load
' method. 

jsonStr = "{ ""numbers"" : [ [""even"", 2, 4, 6, 8], [""prime"", 2, 3, 5, 7, 11, 13] ] }"


success = json.Load(jsonStr)
If (success <> True) Then
    Debug.Print json.LastErrorText
    Exit Sub
End If

' Get the value of the "numbers" object, which is an array that contains JSON arrays.

Set outerArray = json.ArrayOf("numbers")
If (json.LastMethodSuccess = False) Then
    Debug.Print "numbers array not found."
    Exit Sub
End If


numArrays = outerArray.Size

For i = 0 To numArrays - 1


    Set innerArray = outerArray.ArrayAt(i)

    ' The first item in the innerArray is a string
    Debug.Print innerArray.StringAt(0); ":"


    numInnerItems = innerArray.Size

    For j = 1 To numInnerItems - 1

        Debug.Print "  "; innerArray.IntAt(j)
