Hi Abhijit, Can you please attach your original and expected output in the proper format so I can understand your actual data format and may I can help you. Currently, In your posted question I cant identify proper data. You should give your original and expected sample data in a proper tabular manner. Thank you.

Hello, Refer the following code: // Create connection string variable. Modify the "Data Source" // parameter as appropriate for your environment. String sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Server.MapPath( "../ExcelData.xls" ) + ";" + "Extended Properties=Excel 8.0;" ; // Create connection object by using the preceding connection string. OleDbConnection objConn = new OleDbConnection(sConnectionString); // Open connection with the database. objConn.Open(); // The code to follow uses a SQL SELECT command to display the data from the worksheet. // Create a new OleDbCommand to return data from the worksheet. OleDbCommand objCmdSelect = new OleDbCommand( "SELECT * FROM myRange1" , objConn); // Create new OleDbDataAdapter that is used to build a DataSet // based on the preceding SQL SELECT statement. OleDbDataAdapter objAdapter1 = new OleDbDataAdapter(); // Pass the Select command to the adapter. objAdapter1.SelectCommand = objCmdSelect; // Create new DataSet to hold information from the worksheet. DataSet objDataset1 = new DataSet(); // Fill the DataSet with the information from the worksheet. objAdapter1.Fill(objDataset1, "XLData" ); // Bind data to DataGrid control. DataGrid1.DataSource = objDataset1.Tables[0].DefaultView; DataGrid1.DataBind(); // Clean up objects. objConn.Close(); Refer to this article: https://www.c-sharpcorner.com/article/export-and-import-excel-file/ https://www.aspsnippets.com/Articles/Read-and-display-data-from-an-excel-file-xls-and-xlsx-in-ASPNet.aspx https://www.syncfusion.com/blogs/post/6-easy-ways-to-export-data-to-excel-in-c-sharp.aspx https://docs.microsoft.com/en-us/troubleshoot/dotnet/csharp/query-excel-data-aspx-page

your requirement is very simple , as you really need a simple pivot after grouping them Fetch your SQL Server data into a datatable and pivote it and then export as excel public void PullData() { string connString = @ "your connection string here" ; string query = "select Hatch,Deck,Orgzn, Sum(Num) from table group by Hatch,Deck,Orgzn,Num; using (SqlConnection conn = new SqlConnection(connString)) { SqlCommand cmd = new SqlCommand(query, conn); conn.Open(); DataTable dt= new DataTable(); // create data adapter SqlDataAdapter da = new SqlDataAdapter(cmd); // this will query your database and return the result to your datatable da.Fill(dt); var mydt= PivoteDataTable(dt); using (XLWorkbook wb = new XLWorkbook()) { wb.Worksheets.Add(mydt, "myTable" ); Response.Clear(); Response.Buffer = true ; Response.Charset = "" ; Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" ; Response.AddHeader( "content-disposition" , "attachment;filename=SqlExport.xlsx" ); using (MemoryStream MyMemoryStream = new MemoryStream()) { wb.SaveAs(MyMemoryStream); MyMemoryStream.WriteTo(Response.OutputStream); Response.Flush(); Response.End(); } } } } } public static class PivoteDataTable { public static DataTable Pivot( this DataTable tbl) { var tblPivot = new DataTable(); tblPivot.Columns.Add(tbl.Columns[0].ColumnName); for ( int i = 1; i { tblPivot.Columns.Add(Convert.ToString(i)); } for ( int col = 0; col { var r = tblPivot.NewRow(); r[0] = tbl.Columns[col].ToString(); for ( int j = 1; j r[j] = tbl.Rows[j][col]; tblPivot.Rows.Add(r); } return tblPivot; } } Notice :- to export as excel i have used closedXML library which you can downlod from nuget or https://www.microsoft.com/en-in/download/details.aspx?id=5124
