Numbers
If I download an Excel file in the xlsx format, Numbers opens it just fine. If the file is in the xls format it opens in Numbers like this:
<HTML xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel">
<head>
<style>
<!--
table
{
mso-displayed-decimal-separator:"\.";
mso-displayed-thousand-separator:"\,";
Is there something I need to do to be able to use .xls files?
