' Get the "tags" array, which contains "home", 22, "green"

Set tagsArray = json.ArrayOf("tags")

    Debug.Print "tags member not found."
    Exit Sub
End If

' Get the value at each array index. 
' Output will be:
' [0] = home
' [0] as integer = 0
' [1] = 22
' [1] as integer = 22
' [2] = green
' [2] as integer = 0


arraySize = tagsArray.Size

For i = 0 To arraySize - 1


    sValue = tagsArray.StringAt(i)

    Debug.Print "["; i; "] = "; sValue


    iValue = tagsArray.IntAt(i)
    Debug.Print "["; i; "] as integer = "; iValue

Next

' Note: The StringAt method returns the value as a string regardless of the type.

' The IntAt method returns the value as an integer.  If the value does not convert to 
' an integer, then 0 is returned
