Transform a VBA module in a compiled Add-In for Excel

Good morning.
For a technical application I'm using Excel 2013 as a user interface, to show inputs and results with tables and charts.
In this VBA project, calculations are made in a large module that contains only subroutines for number-crunching.
In these subroutines the inputs and outputs are Public variables and there is no reference to Excel objects.
I would like to turn this VBA module in a compiled Add-In, running under the Main program written again in VBA.

Question: what is the easiest way to create this compiled add-in and how to do it?

I don't know C++, but I read somewhere that you can create compiled add-ins for Excel also using VBA.
I would be grateful if you could advise me some papers which explain the best procedure in VB or VBA, in a simple and comprehensive way, with examples step by step.

Any suggestion will be welcome.
Thanks and regards.
Lucio

Thanks for the warning

Regarding your answer, it is understood that a XLAM is not the solution.

I want to turn a VBA module of math., with no reference to Excel objects, in a compiled Add-in, quick, safe and simpler to deploy.

• Keeping in mind that I don't want to automate Excel objects, but only subroutines for numeric calculations, I would like to know if it is preferable a COM, a DLL or something else.

• I would like to know also if it is really necessary to compile with VB (as for example I read that you can create COM files in a simpler way, with VBA).

I hope that it is clearer now.
Finally, I would be grateful if you could also advise me documents on what you feel is the best procedure for my target.

Thanks and regards.
