Add-in Development


Seamless Integration
Extending Microsoft Excel Functionality
An Excel add-in contains code to extend Excel's functionality, usually in the form of new functions, custom ribbon or toolbar buttons. Once an add-in is deployed to your Excel environment, the new functions and buttons are available to all of your Excel workbooks to automate your repetitive tasks and processes. Excel add-ins can be created with:
Excel using the VBA programming language
VSTO using .NET programming languages

Add-Ins Created in VSTO
VSTO is a set of development tools available with Microsoft Visual Studio that supports the Microsoft .NET Framework. It is used by developers to write code connecting Microsoft Office applications. Developers using VSTO can use .NET languages, instead of using VBA. VSTO add-ins are installed on a PC and are compiled applications. From a security point of view, VSTO created add-ins are perfect for distributing code that you want to protect.

Which Add-in Is Best for You?
Firstly, it is important to consider whether an add-in is the right solution for you. If the code you need is required for all workbooks, then an add-in could be a smart choice.
If the add-in features are for your organisation only and security and deployment won't be a barrier for you, then a simple VBA add-in will suit your needs, otherwise a VSTO add-in may be required.
