Hi sbailey,
In order to save your filter criteria and re-use it, we have to use Excel
VBA. A simple way to do that is to use the built-in Excel macro recorder.
Before you auto-filter your data, click on Tools > Macro > Record New Macro
(Excel 2003). Then, perform your filtering. Once done, stop the macro
recording.
At this point, Excel have just saved your steps that you have just recorded
and you may re-play it by using Tools > Macro > Macros and selecting the
macro you have just recorded.
Try it on a new set of data and see if it works.
Thank you.
Regards,
Victor LAN
