See attached message.
I get this every time I download an Excel spreadsheet generated in php with the following header:
header("Content-type: application/vnd.ms-excel")
;
$fn = "registrants" . date('Y-m-d_h_i') . ".xls";
header("Content-Dispositio
n: attachment; filename=" . $fn);
If I change the file extension to xlsx will that solve this?
Thanks

the spreadsheet is fine; it downloads & opens fine in Excel 16.
it's just the confusing message.
the customer gets confused.
