XLW XLW wraps the Excel C API in a simple C++ interface which you can use to customize Excel with your own worksheet formulas and menu items.

Overview

XLW hides the complexity of Excel's C interface, allowing easy implementation of spreadsheet addins. Using XLW, you can take functions implemented in C or C++ and quickly expose them as Excel worksheet formulas.
