Hi
You can read and parse XLS files (only works with xls-files) with urlloader and a ZIP-lib that can read zip-files.
public function loadXLS(url:String):void
            var urlLoader:URLLoader = new URLLoader();
            urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
            urlLoader.addEventListener(Event.COMPLETE, onLoadComplete);
            urlLoader.load(new URLRequest(url));
        private function onLoadComplete(even:Event):void
            urlLoader.removeEventListener(Event.COMPLETE, onLoadComplete);
            model.sheetsDict = new Dictionary();
            var zipFile:ZipFile = new ZipFile(urlLoader.data);
            for(var i:int = 0; i < zipFile.entries.length; i++)
                var entry:ZipEntry = zipFile.entries[i];
                var data:ByteArray = zipFile.getInput(entry);
                if(useFile(entry.name, "/sheet([^$]+)"))
                    model.sheetsDict[entry.name.split("xl/")[1]] = new XML(data.toString());
                else if( useFile(entry.name, "/sharedStrings.xml") )
                    model.sharedStrings = new XML(data.toString());
                else if( useFile(entry.name, "/workbook.xml$") )
                    model.workbook = new XML(data.toString());
                else if( useFile(entry.name, "/workbook.xml.rels") )
                    model.rels = new XML(data.toString());
            trace(model.sharedStrings)
to read the xml properly you have to use namespaces in the reader-class
namespace ns1 = "http://schemas.openxmlformats.org/spreadsheetml/2006/main";
        use namespace ns1;
        namespace ns2 = "http://schemas.openxmlformats.org/officeDocument/2006/relationships";
        use namespace ns2;
        namespace ns3 = "http://schemas.openxmlformats.org/markup-compatibility/2006";
        use namespace ns3;
        namespace ns4 = "urn:schemas-microsoft-com:mac:vml";
        use namespace ns4;
        namespace ns5 = "http://schemas.openxmlformats.org/package/2006/relationships";
        use namespace ns5;
