This is the only way to truly protect your workbook algorithms. This calculation engine substitutes Excel’s original calculation in the compiled EXE, while the Excel itself is used for formatting and reflection of calculation results. In order to protect your workbook algorithms from being copied, we have developed our own formula calculation engine. You can compile an Excel spreadsheet into an EXE application with securely protected formulas in binary format and protected VBA code.
Excel Compiler offers an easy and hassle free workbook copy protection for Microsoft Excel.
