Can we export to excel with sheets?

I have a report that shows different dates, like current date or previous (rolling). they would like instead of a column for Current date, that would be sheet1,

other dates would be if past 7 days  (weekly) sheet 2. if more than 7 days Sheet 3.

I have only ever exported the entire report. What comes to mind is using sub programs but how to export in sheets?

Current report:

order#    orderdate current         order date previous

123        10/21/14                     

234                                           10/18/14

345                                            9/1/14

so the first row would go to sheet 1. the second to sheet 2. and the third to sheet 3.
