CODE :

var dba = _getDB("sun.jdbc.odbc.JdbcOdbcDriver", "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ=C:\\CheckNames.xls;readOnly=false", "", "");

var $selectCount;
var $categories;
_set($selectCount, _byClassName("searchBarComponentOptions", "select").length);

for (var $k=1; $k<$selectCount; $k++){
_set($categories, _getText(_select(0).options[$k]));
_setSelected(_select(0), $categories);
_click(_div("Search >"));
if (_condition(_exists(_select("viewItemsPerPage"), "View All"))) {
_setSelected(_select("viewItemsPerPage"), "View All");
_setSelected(_select("searchSort"), "Price: Low to High");
}



for (var $i=0; $i<100; $i++){
var $el = _div("itemGridTitle[" + $i + "]");
if (_condition(!_exists($el))){
break;
}
var $Temp;
_set($Temp, _getText($el));
$Temp1 = $Temp.replace(//g, "~");
_alert("insert into [Sheet1$] (RowNumber, CatCode, ItemName, category, Exists) values ('"+ $i + "', '" + $k + "', '" + $Temp1 + "', '" + $categories + "', 'T')");
dba.update("insert into [Sheet1$] (RowNumber, CatCode, ItemName, category, Exists) values ('"+ $i + "', '" + $k + "', '" + $Temp1 + "', '" + $categories + "', 'T')");
