Dear friend,
Pass dataset, filename and Worksheet name ...........

Look into the following code

private void ExportToExcel(DataTable dt, string fileName, string worksheetName)
   {
       Response.Clear();
       Response.AddHeader("content-disposition", "attachment;filename=" + fileName + "");
       Response.ContentType = "application/vnd.ms-excel";

       StringWriter stringWriter = new StringWriter();
       HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWriter);
       DataGrid dataExportExcel = new DataGrid();
       dataExportExcel.ItemDataBound += new DataGridItemEventHandler(dataExportExcel_ItemDataBound);
       dataExportExcel.DataSource = dt;
       dataExportExcel.DataBind();
       dataExportExcel.RenderControl(htmlWrite);
       StringBuilder sbResponseString = new StringBuilder();
       sbResponseString.Append("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"> <head><meta http-equiv=\"Content-Type\" content=\"text/html;charset=windows-1252\"><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>" + worksheetName + "</x:Name><x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head> <body>");
       sbResponseString.Append(stringWriter + "</body></html>");
       Response.Write(sbResponseString.ToString());
       Response.End();
   }

   void dataExportExcel_ItemDataBound(object sender, DataGridItemEventArgs e)
   {
       if (e.Item.ItemType == ListItemType.Header)
       {
           //Header Text Format can be done as follows
           e.Item.Font.Bold = true;

           //Adding Filter/Sorting functionality for the Excel
           int cellIndex = 0;
           while (cellIndex < e.Item.Cells.Count)
           {
               e.Item.Cells[cellIndex].Attributes.Add("x:autofilter", "all");
               e.Item.Cells[cellIndex].Width = 200;
               e.Item.Cells[cellIndex].HorizontalAlign = HorizontalAlign.Center;
               cellIndex++;
           }
       }

       if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
       {
           int cellIndex = 0;
           while (cellIndex < e.Item.Cells.Count)
           {
               //Any Cell specific formatting should be done here
               e.Item.Cells[cellIndex].HorizontalAlign = HorizontalAlign.Left;
               cellIndex++;
           }
       }
   }

Hi
Use iTextSharp to conver Gridview to PDF:

HTML convert to PDF using itextsharp[^]

For Excel:

protected void btnExpExcel_Click(object sender, EventArgs e)
        {
            Response.ClearContent();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Report.xls"));
            Response.ContentType = "application/ms-excel";

            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);

            DataTable dt = new DataTable();
            dt = (DataTable)Session["dtReport"];

            gvMISReport.AllowPaging = false;

            gvMISReport.DataSource = dt;
            gvMISReport.DataBind();

            //Change the Header Row back to white color
            gvMISReport.HeaderRow.Style.Add("background-color", "#FFFFFF");
            
            //Applying stlye to gridview header cells
            for (int i = 0; i < gvMISReport.HeaderRow.Cells.Count; i++)
            {
                gvMISReport.HeaderRow.Cells[i].Style.Add("background-color", "#157CB0");
            }
            int j = 1;
            
            //This loop is used to apply stlye to cells based on particular row
            foreach (GridViewRow gvrow in gvMISReport.Rows)
            {
                gvrow.BackColor = Color.White;
                if (j <= gvMISReport.Rows.Count)
                {
                    if (j % 2 != 0)
                    {
                        for (int k = 0; k < gvrow.Cells.Count; k++)
                        {
                            gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
                        }
                    }
                }
                j++;
            }
            gvMISReport.RenderControl(htw);
            Response.Write(sw.ToString());
            Response.End();
        }
