UsedRange.Cells.Rows.Count;       for (Var i=row_start;i<=colcount;i++) {      typeof   if (Osheet.cells (i,8). Value) = = ' Date ' {/////////= read problem with date format for part 8th column cell content             d= new Date (Osheet.cells (i,8). Value );            Temp_time=d.getfullyear () + "-" + (D.getmonth () + 1) + "-" +d.getdate ();        }         else             Temp_time=$.trim ( Osheet.cells (i,7). value.tostring ());         tempstr+= ($.trim (Osheet.cells (i,2). Value) + "+$.trim (Osheet.cells (i,4). Value) +" "+$.trim (Osheet.cells (i,6). Value.tostring ()) + "" +temp_time+ "n");        /Read 2nd, 4, 6, 8 column content    }       return tempstr; return     oxl.quit ();     CollectGarbage (); {</script>         must be conditional:   1, the client must have the Microsoft Excel ActiveX control installed (complete Microsoft Office installed), and The browser pops up "This site needs to run the following add-ins ..."
