Make multiple copies of a worksheet in an Excel file
I have an Excel file with one worksheet named "Sheet1". Sheet1 contains a "shell". I need the file to contain 20 copies of Sheet1 and the tabs to be named by the numbers 1 through 20. In other words, rename Sheet1 to "1" and make 19 additional copies of it numbered 2 through 20. The expected result is an Excel file with 20 tabs numbered 1 through 20; each containing a copy of the "shell" from Sheet1.
