The following macro copies an Excel sheet to a custom template. All you need do is set the template path to your own or a network drive. This is really only a snippet to demonstrate the concept but is a complete macro nonetheless. I've used it within a more complex process to generate invoices from a data file, then copy each invoice to a separate file to email out as an attachment. This was a temporary solution during the lead up to a billing system change for a Telecoms client. 

I've used this to get around not being able to copy headers and footers in Excel and to avoid copying common drawing objects such as a logo and text boxes. By having these set in the template I didn't need to copy them each time the process looped.
