COM and VSTO add-ins represent traditional Office integration solutions designed exclusively for Windows-based Office environments. In contrast, Office Add-ins are web-based and don’t require code execution on the user’s device or within the Office client itself. With an Office Add-in, the respective Office application, such as Excel, reads the add-in’s manifest file and integrates its custom ribbon buttons and menu commands seamlessly into the user interface. When necessary, it loads the add-in’s JavaScript and HTML code, running them securely within a browser or webview control in a controlled environment.
