I did something like this. I was taking an office computing class which taught us Excel, so I used my "skills" to make a chart for my students to monitor their progress. Since I was instructing for a 141 school, we had VERY detailed flight lessons and hour requirements. By using the Excel spreadsheet, it easily totalled up how much time each student had for Total, Night, Sim Inst, Landings, etc.
I don't have the file anymore, otherwise I would forward it to you!
