Re: Formatting in XLS(X) files

Erratum:

This line is corrected thus:

(* Reset the numeric values to get the correct type *)
worksheet@Range["E6:E9"]@Value = List /@ Rest[data[[All, 1]]];

The reason it is there at all is that the data in

srcRange@Value = data;

is of mixed types, and Excel receives it all as text.
