Try the following code, it is a bit of a hack and it seems to work with IE7. However, it will not work with other browsers because they will not show the file path. Other browsers will also never be able to show the ActiveXObject (Excel).

<!DOCTYPE html>
<html>
<head>
<body>
<div id="divHidden" style="visibility: hidden; width: 0px; height: 0px">
  <input type=file id="fileInput">
</div>
<input type=button value="click here to get a file" onclick="readdata(1,1);">

<script language=javascript>

    function readdata(y,x) {

        // Use the <input type='file'...> object to get a filename without showing the object.
        document.all["fileInput"].click();
        var fileName = document.all["fileInput"].value;

        try {
            var excel = new ActiveXObject("Excel.Application");
            excel.Visible = false;
            var excel_file = excel.Workbooks.Open(fileName);

            var excel_sheet = excel_file.Worksheets("Sheet1");
            //  var data = excel_sheet.Cells(x, y).Value;
            var data;
            for (; excel_sheet.Cells(x, y).Value.length > 0; x++){
                data[i][0] = excel_sheet.Cells(x, y).Value;
                data[i][1] = excel_sheet.Cells(x, y+1).Value;
            }
            drawWithexcelValue(data);
        }
        catch (ex) {
            alert(ex);
        }

        // This will show the data.
        alert(data);

    }

</script>
</body>
</html>
