Ausführung von Excel-Arbeiten -- 2

I have an excel list of approx 4900 Swiss Postal Codes (ZIP code) for which I need the exact distance in KM from our two warehouses in Germany. The distance from Google Maps is needed for all of these Zip Codes. I guess this should be a rather easy task with a VBA in Excel, but I cannot do it. You definitely need to program it in Excel (VBA). No manual look up wanted. There will be more tasks to come if you can help me with this.
