PT Session Notes Excel Export - Tabulating $ Won/day

[Lmn55d]

Ok, trying to get this tax stuff in order. I just exported my session notes in Poker Tracker to excel. Now I have 4 columns : Session start time (date , time), session end time, level, and $ won.

Is there any way to find out how much I won per day? In other words can I sum all the rows that are within one day to find out how much I won on 7/9/05 for instance?
