                   IWorkbook workbook = application.Workbooks.Open(fileStream);
   
                   IWorksheet worksheet = workbook.Worksheets[0]; 
   
                   IWorksheet pivotSheet = workbook.Worksheets.Create("PivotSheet"); 
   
                   //Create a Pivot cache with the given data range.
   
                   IPivotCache cache = workbook.PivotCaches.Add(worksheet["A1:H50"]); 
   
                   //Create "PivotTable1" with the cache at the specified range.
   
                   IPivotTable pivotTable = pivotSheet.PivotTables.Add("PivotTable1", pivotSheet["A1"], cache); 
   
                   //Add Pivot table row fields.             
   
                   pivotTable.Fields[3].Axis = PivotAxisTypes.Row;
   
                   pivotTable.Fields[4].Axis = PivotAxisTypes.Row; 
   
                   //Add Pivot table column fields.
   
                   ivotable.Fields[2].Axis = PivotAxisTypes.Column; 
   
                   //Add data fields.
   
                   IPivotField field = pivotTable.Fields[5];
   
                   pivotTable.DataFields.Add(field, "Units", PivotSubtotalTypes.Sum); 
   
                   field = pivotTable.Fields[6];
   
                   pivotTable.DataFields.Add(field, "Unit Cost", PivotSubtotalTypes.Sum); 
   
                   //Pivot table style.
   
                   pivotTable.BuiltInStyle = PivotBuiltInStyles.PivotStyleMedium14;           
   
                   string fileName = "PivotTable.xlsx";
   
                   //Saving the workbook as a stream.

                   workbook.SaveAs(stream);
