I have used MS Excel for many years as a Financial Controller in glass production and electronic manufacturing. I do on a daily and weekly bases different reports, can record some level macros. I can prepare sales reports > actual + orders vs forecast (budget). Material purchase price analysis, direct work analysis, fixed costs analysis, stock report > raw materials, semi-finished goods, finished goods. I attached my Master's thesis infographic of the results. This was combined work with MS Excel and gretl.
