                    Request.Files[0].SaveAs(Server.MapPath(savedFileName));

                    var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=Excel 12.0;", Server.MapPath(savedFileName));
                    var conn = new OleDbConnection(connectionString);
                    conn.Open();

                    var schema = conn.GetSchema("Tables");
                    var sheetName = schema.Rows[0]["TABLE_NAME"].ToString();
                    var selectStatement = string.Format("SELECT * FROM [{0}]", sheetName);
                    var adapter = new OleDbDataAdapter(selectStatement, connectionString);
                    var ds = new DataSet();

                    adapter.Fill(ds, "results");
                    var data = ds.Tables["results"];

                    adapter.Dispose();
                    conn.Close();
