Hi Jimmy,


Thank you for using Syncfusion products.


Your requirement of exporting formatting columns and Custom type summaries can be achieved by using FormatExcelCellHandler event. Please refer to the following code snippets:




GridExcelExport excel = new GridExcelExport(this.GridGroupingControl1, "excel.xls");

        excel.ExportNestedTable = true;

        excel.FormatExcelCellHandler += new ExportExcelCellHandler(excel_FormatExcelCellHandler);





void excel_FormatExcelCellHandler(object sender, ExcelExportEventArgs e)


        if (e.RowElement.IsRecord() && e.ExcelCell.Column == 3)   // check specific column


            e.ExcelCell.Cells[0].NumberFormat = "0.0%";   // set the format accordingly



        if (e.RowElement.Kind == DisplayElementKind.Summary)


           // you can process for custom summaries here




Please find sample from the attachment for your convenience.



Please try this and let us know if you have any other queries.
