I am using the following code to import data using Excel sheet. It is working fine in localhost, but not in server. I d't know the reason. The file is storing in a folder, but the data fetching and saving in database is not happening. Is the server need to install the MS Excel ?.the oconn.Open() function is not happening,from their only the error is comming..Plz gve me a solution.

string extension = Path.GetExtension(FileUpload1.FileName);
                filename = DateTime.Now.ToString("dd-MM-yyyy") + "_" + DateTime.Now.Hour + "_" + DateTime.Now.Minute + "_" + DateTime.Now.Millisecond + extension;
                FileUpload1.SaveAs(Server.MapPath("~/Account/PublishedRanklist/") + filename);
                string path = Server.MapPath("~/Account/PublishedRanklist/" + filename);
                OleDbConnection oconn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=Excel 8.0");
               
                    OleDbCommand ocmd = new OleDbCommand("select * from [Sheet1$]", oconn);
                    oconn.Open();
                    OleDbDataReader odr = ocmd.ExecuteReader();
                    while (odr.Read())
                   {       int Regno=valid(odr, 0);

                   }

                  oconn.Close();

protected string valid(OleDbDataReader myreader, int stval)//if any columns are found null then they are replaced by zero
        {
            object val = myreader[stval];
            if (val != DBNull.Value)
                return val.ToString();
            else
                return Convert.ToString(0);
        }
