SUMMARY
In Microsoft Excel you can programmatically list the dynamic link library (DLL and XLL) files that provide functions registered in Excel.

This article describes a sample macro that creates a three-column array of all registered functions in Microsoft Excel, where column 1 displays the name of the DLL or code resource; column 2 displays the name of the procedure in the DLL or code resource; and column 3 displays strings specifying the data types of the return values, and the number and data types of the arguments.
