Excel has to be open to do any of that.

You can use the application.Ontime

You could put this in a file in the xlstart directory and have windows
schedular open that file at a specified time. Put code in the workbook_Open
event to run a macro to do your work

http://www.cpearson.com/excel/events.htm
for an overview of events

YOu can use the data in the file name

sName = "C:\Myfolder\Myfile" & format(date,"yyyymmdd") & ".xls"
activeworkbook.SaveCopyAs sName

Is there a way to program a file in excel to use the SaveCopyAs

The filename will remain constant and the older file will be deleted
first (Kill).

Now an even harder question - can you program excel to do this and save
it as a different file everyday?

Either one of these solutions would save me much time and labor. Thank
you.
