How can I call a function defined in a COM Addin using excel macro ?
Basically I have created a Excel COM Addin which does some bunch of stuff.
Now I want to invoke this via excel macros.
Is it possible to do it ?
Or
Is it possible to install COM Addin using a macro ?
You can reference COM libraries in the VBA editor by going to tools -> references (I think) then you can select (or browse for) whatever DLL you've created. When you've selected it there you can use the functions contained within in the usual way.
You should see a big list of libraries to select from.
When I've done VBA development in the past I normally end up using a few things like the Microsoft XML libraries through this method.

I'm maintaining a legacy Excel workbook that has a significant amount done in VBA. For threading's sake, I need to move some of that work out of VBA. I have prototyped a DLL written in C#, but deployment (with registration) is more difficult.
Can you interact with the new HTML5 style add-ins using VBA? So, in this case, writing a function in Javascript, and then calling it with specific parameters from the existing VBA macro. If so, how?
Unfortunately this is not a scenarios supported by Microsoft nowadays.
I understand it is very well possible to write scripts in VB.Net which are able to create/manipulate Excel application and its object structure. Is there a workaround that would allow one to include or otherwise integrate the VB.Net code into a particular workbook so that a regular user could run it? E.g.:
Having the script in VB.Net in a separate file next to the Excel file and call it through VBA.
Inserting the VB.Net script file into the workbook (like one can insert any other file) and then running it by double-clicking it
The aim is to go around some of the limitations and archaisms of VBA as well as being able to use some more modern and user-friendly IDE (such as VSCode) instead of the built-in VBE.
This may be a silly question - I haven't found anything on Google about this. No new programs populate in the task manager when VBE is opened from an Office Application, and I don't see an executable that looks probable. DLL maybe?
Some Office applications provide the Run method for the Application class. For example, see Run Excel Macro from Outside Excel Using VBScript From Command Line.
Yes, you can call VBA macro at runtime.
There are applications that don't provide any specific methods for that, for example, Outlook. In that case you can use the late-binding technology (see Type.InvokeMemeber) - see Calling Outlook VBA Macro from outside (VB/VBScript/C#).
You can invoke a CommandBarButton's OnAction macro as a proxy for Application.Run.
For details, see this question How can I run a macro from a VBE add-in, without Application.Run?
I want to manipulate data in excel with some complex functions.
It seems that I have to use VBA.
However I don't want to learn it.
Is there any other way to do programming in the excel? Some language like C#?
I don't want to create a independent C# application using some interface provided by Excel. Only program in excel, like VBA, but a different language.

You cannot unfortunately. To program in Excel from within Excel you will have to learn VBA.
To program for Excel, be it VBA, VSTO(C#, VB.Net) you need to understand the Excel Object Model (EOM) without which you cannot do programming for Excel.
You don't need to learn VBA per se if you want to develop Office solutions from C# but as you become familiar with the EOM, you will notice that you automatically develop an understanding for VBA.
EDIT
Excel Object Model from Excel's perspective
Excel Object Model Overview from VS's perspective
You can develop Excel "Add-Ins" in C# using VSTO - Visual Studio Tools for Office (MSDN link).
This is not truly "inside Excel," but once installed your add-in can run without having to start up any external application.
Excel has a VBA editor built in to use VBA only.
If you want to use another language it would need to be external.
While you could make a C# add in, this is not in the built in editor as you described.
To the best of my knowledge, you simply cannot do this right now. In Office 15 it looks as though you'll be able to use JS:

I just started to learn VBA. As far as I understood, one uses VBA to write macros in MS-Excel. But I wonder if it the only area of application for VBA. Can it be also used like many other standard languages - like Python, for example.
If it is the case, how can I compile a VBA program? Should it be compiled? How can I run such a VBA program?
VBA is compiled to p-code. P-code is an intermediate language that requires an additional runtime in order to execute. This runtime is hosted by most Microsoft Office applications (including various non-Microsoft applications).
In short, you cannot write a VBA only app that is compiled to an .EXE.
To create a stand-alone VBA-like program, you would need to use Visual Basic 6 or earlier. The successor of Visual Basic 6, of course, is VB.NET, which is a very different animal.
VBA can be licensed, and there are quite a few pproducts outside office that use VBA. MS no longer issues new licenses. There are non-MS VBA implementations, like from Summit software. In any case you need to have your own product that would host VBA.
A notable application supporting VBA is AutoDesk AutoCAD. It licenses the VBA runtime and has its own object model.
If you don't compile the program ahead of time (in the Visual Basic Editor click Debug -> Compile), then Microsoft Office compiles it at run time. You really should compile frequently though because that is how you find compile errors.
How you run a VBA application depends entirely on how you have set it up to run. In Excel for example you can have the Workbook_Open event start your code when the workbook is opened or create custom menus that users click on to run the code. In Access, you can set a form to display when the database opens or create an autoexec macro that will run when the database opens. etc. etc.
Like someone else said above, you can't create .exe files of VBA. The code has to run in a Microsoft Office Application.
