I think calc4web (1) translates Excel functions into C++ functions and (2) compile them into a DLL that can be called from Excel.<br />
<br />
Step (1) is easy... Any Excel functions can be translated into C++ functions.<br />
<br />
Step (2) you need <a href="https://docs.microsoft.com/en-us/office/client-developer/excel/welcome-to-the-excel-software-development-kit" rel="ugc">Excel C API</a> &nbsp;from Microsoft.<br />
<br />
Step (2) requires a lot of work. Fortunately, there is <a href="http://xlw.sourceforge.net/index.shtml" rel="ugc">a C++ Wrapper</a> that will take care of that. Now, you just focus on writing the C++ functions, and the Wrapper will take care step (2) for you.

We would like to find a way to automatically convert an excel workbook into c++ code.<br />
The following tool apparently does that (calc4web) however it generates a compiled .dll intead of C++ code.<br />
We want to be able to reuse and enhance the c++ code.<br />
Anyone used this before? Are there any other out of the box solution out there ?<br />
If not, is there a way or a tool &nbsp;to map the entire workbook so that we can follow it like a blue print and then convert it to c++<br />
Any ideas or solutions would be very helpful

Convert Excel Workbook into c++ code

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

Microsoft Excel

Microsoft Office is an integrated suite of applications that includes Outlook, Word, Excel, Access, PowerPoint, Visio and InfoPath, along with a number of tools to assist in making the individual components work together. Coding within and between the projects is done in Visual Basic for Applications, known as VBA.
