I was recently wanted to move six individual sheets from an Excel workbook into their own separate workbooks. When I moved each sheet, I gave its new workbook a unique name. I successfully repeated this 5 times, but when I tried to do it the 6th sheet I got an error message. I failed to realize that I was trying to move the only remaining sheet from the workbook. Being smarter than I was, Excel wouldn’t allow me to move the final sheet from the original workbook and leave it with no worksheet! It finally dawned on me that I could just save the original workbook that now contained only the final sheet, give it it’s own name, and be done. Doh!
