The question is: how did you come to displaying any tags in first place?

First of all, please put code in the question, not comments. (Click "Improve question" above.)
And still, nobody can see how did you export. Probably you don't want to show any tags at all, only content.

All right, if you don't want to show you C# code, don't. But why asking questions then?

[HttpPost]
public ActionResult GetFile(ExcelModel excelModel)
{
Session["tableData"] = Regex.Replace(excelModel.HtmlStrings, @"(<img\/?[^>]+>)", @"", RegexOptions.IgnoreCase);
return Content("");
}

public ActionResult getSessionData()
{
Response.AddHeader("Content-disposition", "attachment; filename=NCBC.xls");
Response.ContentType = "application/octet-stream";
string one = Session["tableData"].ToString();
return Content(Session["tableData"].ToString());
}

Session["tableData"] has html table data which has tags with td display:none .... now I want to remove the tags from Session["tableData"] which has td with display:none . So that while exporting it will be not exported .

I love regular expressions also, but why not just use a simple if with a string contains? The regex seems like extreme overkill given the simple issue.
