If you've created an Excel spreadsheet that performs calculations, you can create an executable program using the XCell Compiler utility. This will allow you to share the spreadsheet as a program file, obscuring the underlying formulas that make the calculations in binary format. You can also add your own splash screen, program icon and a license agreement that users must agree to in order to use the program.
