Well, taking advantage from the bad weather in Roma I did not go sailing but stayed in front of the fireplace...messing up with the excel POI maker.
Great work by Kiwi. I studied the macro and learned a lot.
I only have one question so far. The heading of the file is always "Gphi" even if I select HIGH. Nevertheless I modified the macro to have "Glambda". I guess it is not a critical item, but it is just to understand why it does not work...soon I will test the output files and post the results.
