I have a workbook with, say, 5 sheets (could be variable numbers of sheets)
all with the the EXACT same structure (column headers), but with vary data
and numbers of rows. I would like to automate the process of concatenating
all the sheets into one "massive" worksheet. At that time, I will be doing a
lot of other "stuff" to that massive sheet, but I need to get it there,
first.

Any ideas on a simple way to concatenate a "variable" number of worksheets
in a workbook, into either a new workbook, or, simply another worksheet (n+1
worksheets, where n= the original number of worksheets) in the same workbook?

Probably simple, but not for a noob like me. Thanks!
