Hi!
I'm interested in the project.
I'll need more details about what is it exactly want you need to do in excel, but whatever it is I can do it :D
I can build my own macros, VBA code or additional programs and scripts to work very efficiently, I'm a physics student so working with huge complex data of any kind is second nature to me.
I'm kinda new in this site, but If you wish you can take a look at one the articles that is in my portfolio to check my experience :D
As for market expertise, I worked a couple of months in e-commerce taking care of datasheets (stock, modeling, performance, etc), so I'm well aware of how are the business needs in regard of data analysis :)
Anyway, If I got your attention please contact me, I'm available and ready :D
