I want so sell excel spreadsheets online - how can I protect it?

I am currently developing 8-10 rather simple excel spreadsheets for students who study business economics. I want to sell them on a website (i build myself). However, I would like to add copy protection. I researched, and found XLS Padlock, but this program makes an .exe file, and does not run on a macbook. Maybe it is possible, to convert the excel file to .jar or similar, and make it work?

Taidot: Excel, Ohjelmointi
