Sorry, but you did not provide enough information about your issue, like the method you used to export data to MS Excel file, etc. Nevertheless...

If you have about 60K records in 22 columns, Excel file could takes over 16 MB. Using formatting causes successive file growth.

Tip: Next time, please be more specific ;)

Thanks, for replying me
Below code is using to generate excel.

public ActionResult ExportToExcelInvoiceInView(int sno)
{

gvUserInfo.DataSource = Datasource; // Binding with GridView
gvUserInfo.ShowFooter = true;

gvUserInfo.DataBind();

GridViewRow footerRow = gvUserInfo.FooterRow;
Label lbl = new Label();
lbl.Text = footer;
footerRow.Cells[lastColumnIndex].Controls.Add(lbl);

System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
gvUserInfo.RenderControl(htw);
byte[] buf = DocWriter.GetISOBytes(sw.ToString());
return new BinaryContentResult(buf, "Invoice.xls");

}
