I'm no expert in excel but i'll share to you what i know..
1-how do i go about doing V-lookups and what the heck it is ...
Used to search for values that are from different dataset/s. For instance, you have two sets of data (A and B). There are information in B that you'd like to have in A. One of the way to do this is by using the vlookup formula.
2- macros
Created to make complicated things simple (or to make an entire computation/processing automated). Indeed very complex and neither do I have an idea how to create one.
3-pivot tables
To summarize data (and at the same time, edit table formats as one pleases to have a better analysis).
IT peeps, please correct me if I'm wrong. Hope these help.
