Creating Excel AddIn From Visual Studio 2013


Today you will learn to create an application-level add-in for Microsoft Office Excel with the Visual Studio 2013. You can apply it also to create the projects for Excel 2010.

We'll proceed here with the following sections:

  • Project Creation
  • Code Implementation
  • Project Execution
  • Cleaning the Solution


The following are some prerequisites:

  • Excel 2013 or Excel 2010
  • Microsoft Office Development in Visual Studio 2013

Let's proceed with the sections mentioned above.

Project Creation

Code Implementation

There are two methods named ThisAddIn_Startup() and ThisAddIn_Shutdown() created automatically. We need to implement some code to generate the text in the Excel file. Use the following procedure to do that.

Step 1: Modify your code in the ThisAddIn_Startup()

private void ThisAddIn_Startup(object sender, System.EventArgs e)


     this.Application.WorkbookBeforeSave += new Microsoft.Office.Interop.Excel.AppEvents_WorkbookBeforeSaveEventHandler(MyExcelAddIn_BeforeSave);


Step 2: Now generate the method as shown below:

Generate Method

Step 3: Modify your auto generated method with the following code:

private void MyExcelAddIn_BeforeSave(Excel.Workbook Wb, bool SaveAsUI, ref bool Cancel)


    Excel.Worksheet CurrentSheet = ((Excel.Worksheet)Application.ActiveSheet);

    Excel.Range SheetFirstRow = CurrentSheet.get_Range("A1");


    Excel.Range NewSheetFirstRow = CurrentSheet.get_Range("A1");

    NewSheetFirstRow.Value2 = "Visual Studio 2013 by Nimit Joshi";
