Insert Excel rows and columns in C#, VB.NET

Platform: WinForms |
Control: XlsIO |
Published Date: April 30, 2011 |
Last Revised Date: April 10, 2019

Syncfusion Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. Also, converts Excel documents to PDF files. Using this library, you can insert Excel rows and columns in C#, VB.NET.

‘InsertRow’ and ‘InsertColumn’ methods are designed to work if the row index or column index falls within the used range of the worksheet. Also, these methods take input in one based index, and hence to insert a column at ‘A’, you must use worksheet.InsertColumn(1);

As per Microsoft Excel behavior,

  • the merged formats of the previous or next row/column to the inserted one, won’t be copied.
  • the styles and borders applied to the previous row/column will be updated.
  • formulas won’t be updated.

Steps to insert Excel rows and columns, programmatically:

Step 1: Create a new C# console application project.

Step 2: Install the Syncfusion.XlsIO.WinForms NuGet package as reference to your .NET Framework application from NuGet.org.

Step 3: Include the following namespace in the Program.cs file.

    //Add a workbook
    IWorkbook workbook = application.Workbooks.Open("InsertRowsandColumnsTemplate.xlsx", ExcelOpenType.Automatic);
 
    //The first worksheet object in the worksheets collection is accessed
    IWorksheet worksheet = workbook.Worksheets[0];
 
    //Inserting Rows
    worksheet.InsertRow(3);
    worksheet.InsertRow(6);
    worksheet.InsertRow(8);
 
    //Inserting Columns
    worksheet.InsertColumn(2);
    worksheet.InsertColumn(3);
    worksheet.InsertColumn(4);
 
    //Save the workbook
    workbook.SaveAs("Output.xlsx");
}
