I think you need to change the line as below

Response.ContentType = "application/ms-excel";

instead of

C#

Response.ContentType = "application/vnd.ms-excel";

and you need to add these lines

C#

Response.ContentEncoding = System.Text.Encoding.UTF8;
             Response.Cache.SetCacheability(HttpCacheability.NoCache);

and remove the

C#

Response.Flush();

Let me know if it works...

Solution 1

The code seems to be ok, try these two things:

1- Comment the line - Response.Flush();
2- Use Response.Write(sw.ToString()); in place of
Response.Output.Write(sw.ToString());

Let me know how it goes...
