The XLL+ Function Wizard is an addin for Microsoft® Visual Studio™. It makes it easy to create and maintain Excel Add-in functions.

Writing addin functions for Excel in C/C++ is tedious and error-prone, even for the most experienced and conscientious of developers. The developer must write code to:

• Register the add-in library with Excel
• Register each add-in function
• Read each argument and convert it from Excel data format to native C types
• Return errors if inputs do not satisfy constraints regarding shape and content
• Construct and populate a return value in Excel data format

If you use the XLL+ AppWizard to create your Visual Studio project and the XLL+ Function Wizard to create your addin functions, all this code will be generated for you. And if you need to change your function's interface later, the Wizard will modify the generated code as needed.
