csv
basically i have rows after rows of data
event | venue | date | some | other | columns | here|
there are lot of overlapping event that happens at same venue and date.
so i would like to end up with only unique events by matching event, venue, date.
is this possible in excel , how to approach this ? VBA ? or some option i dont know about ?
thank you.
