Like starguy, I'm a little uncertain of exactly what you are trying to do.
Are you working within a single Excel workbook, or between 2 or more of them?
No matter, give this a try:
Choose the existing sheet that has things set up the way you want (you can
even choose several sheets at once, search Help for Group) then from the menu
bar, choose Edit | Move or Copy Sheet and check the [Make Copy] option.
Then, just pick where to put them, in the same book, or in another that is
also open, or even into a brand new book and click OK and you're done. You
can then go to the copied sheets and delete any information you don't want on
them to start fresh.
The [Make Copy] option makes a copy, leaving the originals right where they
were, if you don't choose that option then the sheets are literally moved
(like a Cut operation). If you copy them into the same workbook they will
get a little indicator added to their names. For example, a sheet named
'Sheet1' copied into the same book will be given the name 'Sheet1 (1)' the
first time it's copied, 'Sheet1 (2)' the second time, etc. The original
sheet will not have its name changed.
If this isn't what you were looking for, let us know and we'll try to help
again.
