Can you change the column headers in CSV?

I have a report i built that shows password expiration dates for a list of users.  When i export to CSV, i include the column headers, BUT i want to change the column headers to something more intuitive.  Is that possible?  So instead of a column saying "Domain Name (Domain)", i would just have it say "Domain".  And instead of "Canonical Name (Domain OU)", it would say "Organizational Unit".
