For some reason I have so far been unable to create a default Excel workbook template. I know that the extension must be ".xlt", and that a default workbook template should be stored in "... \XLStart".
Help didn't mention what it should be named, but J. Walkenbach said to name a default workbook template "Book.xlt" and a default sheet template "Sheet.xlt". I did all that, but when I request a new workbook, I get the standard one that Excel always creates. I couldn't find an ".xlt" file that seemed to be the Excel default. What am I missing?
