I have 2 machines, running Excel 2003 and 2007.
I mistakenly trashed the Excel 2003 personal.xls.
The Excel 2007 machine has a personal.xlsb.
How do I convert personal.xlsb to personal.xls?

If I open personal.xlsb in Excel 2003, it is converted, but mangled.
2003 VBE (Visual Basic Environment?) does not have a Save As menu item.
