Generate Excel Bulk Report in Asp.Net With Extension method

To Generate the faster report for bulk data i used following code base for the download the data. Sample Code is :-

Supporting DLL is Click here (ClosedXML.dll)

 if (dtBase != null && dtBase.Rows.Count > 0)

        {

            if (dtBase.Rows.Count > 0)

            {

                dtBase.ExportExcel("VKYC_Report", "VKYC_Report");

            }

            else
