Lets say I have
datatable dt
with all my data inside 'dt'. How can I format the style of it, and export it as an xls file so that I can open it up in excel and it will be formatted correctly?

I have looked at other guides on here such as this one
-- Generating Excel (XML Spreadsheet) in C#[^]--
but they don't really explain much. Any help would be greatly appreciated!

Thanks ~MJ

Take a look the following link.
ASP.NET: Export a DataTable to Excel[^]

Just change the content type to application/xls

context.Response.ContentType = "application/xls";

I hope this helps you well.

Thats CSV and the link to XML is broken.

I need XML XLS because I need to format the excel file.

Solution 3

write the following code under button click :

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=DocumentReport.xls");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ms-excel";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
gvReports.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
