Here ya go - quick and dirty, but it works for me:

Type geoloc
    lat As Double
    lon As Double
End Type

Function GetGeoCode(strAddress As String) As geoloc
    Dim oHTTP As Object
    Dim lngresult As Long
    Dim strPage As String
    Dim strParam As String
    Dim lngPtr As Long
    Dim strFixedAddress As String
    Dim gl As geoloc
    strFixedAddress = Replace(strAddress, vbCrLf, "")
    strFixedAddress = Replace(strFixedAddress, " ", "+")
    strParam = "http://maps.googleapis.com/maps/api/geocode/json?address=" &
_
               strFixedAddress & "&sensor=false"
    Set oHTTP = CreateObject("Msxml2.XMLHTTP")
    lngresult = oHTTP.Open("GET", strParam, False)
    lngresult = oHTTP.Send("")
    strPage = oHTTP.Responsetext
    Set oHTTP = Nothing
    lngPtr = InStr(strPage, """location"" : {") + 20
    strPage = Mid$(strPage, lngPtr)
    lngPtr = InStr(strPage, "},")
    strPage = Left$(strPage, lngPtr)
    strPage = Replace(strPage, " ", "")
    gl.lat = Val(Mid$(strPage, 7))
    strPage = Mid$(strPage, InStr(strPage, """lng"":"))
    gl.lon = Val(Mid$(strPage, 7))
    GetGeoCode = gl
End Function

Function TestGeocode()
Dim strA As String
Dim gl As geoloc
strA = "1600 Amphitheatre Parkway, Mountain View, CA"
gl = GetGeoCode(strA)
MsgBox strA & " is as Lat: " & gl.lat & " and Lon: " & gl.lon End Function
