A better, and more complete way than the OLE version above, is using Image::ExifTool's ImageInfo. This also identifies the new Office file formats with or without extensions:
#!/usr/bin/perl
use strict;
use warnings;
use Image::ExifTool 'ImageInfo';
my @files = (
'test.xls', 'test.xlsx',
'test.doc', 'test.docx',
'test.ppt', 'test.pptx',
);
for my $filename ( @files ) {
my $info = ImageInfo( $filename );
printf( "%-20s = %s\n", $filename, $info->{FileType} );
}
__END__
Output:
$ perl exif_check.pl
test.xls = XLS
test.xlsx = XLSX
test.doc = DOC
test.docx = DOCX
test.ppt = PPT
test.pptx = PPTX
It might seem a little odd using Image::ExifTool for this but it has a large number of recognised formats.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
