Export HTML Table to Excel using ASP.NET

Question

I have an html table (Not Gridview) and that has no proper Header and rows. Instead it has customized structure and data. I want to export this table to Excel. How can I do

Answer 1

If dtReport contains the table(i.e data to be exported) then we can export the table to excel by using the following LOC and also we can format the header

    if (dtReports != null && dtReports.Rows.Count > 0 && !string.IsNullOrEmpty(formName))
            {
                string filename = formName.ToUpper() + ParsConstant.XLS_EXTENSION;
                StringWriter tw = new StringWriter();

                using (HtmlTextWriter hw = new HtmlTextWriter(tw))
                {

                    //Binding Datatable to DataGrid.
                    DataGrid dgGrid = new DataGrid();
                    dgGrid.DataSource = dtReports;
                    dgGrid.DataBind();

                    //Some Properties for the Header
                    dgGrid.HeaderStyle.Font.Bold = true;
                    dgGrid.HeaderStyle.Font.Size = 13;

                    //Get the HTML for the control.
                    dgGrid.RenderControl(hw);


                    Response.ContentType = "application/vnd.ms-excel";
                    Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
                    //Response.Write("");


                    Response.Write(tw.ToString());
                    Response.End();
                }
            }

using MSO Format will not be avoiding leading zero's,but it will convert the text to string which is not advisable for doing operations.
