I'd say you'd definitely want to unpack, as JavaFan mentioned. Something similar to: 
#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

my $rcount = 1;

while (<DATA>) {
   my $string = $_;

   next if $rcount++ < 8;

   my @fields = unpack ('A34 A30 A40', $string);
   print Dumper(@fields), "\n";
}


__DATA__
Ignore Me Line 1
Ignore Me Line 2
Ignore Me Line 3
Ignore Me Line 4
Ignore Me Line 5
Ignore Me Line 6
Ignore Me Line 7
This is a very long sentence which should illustrate the unpacking fun
+ctionality in accordance to what you require.

Outputs: 
$VAR1 = 'This is a very long sentence which';
$VAR2 = ' should illustrate the unpacki';
$VAR3 = 'ng functionality in accordance to what y';

For writing excel spreadsheets, Spreadsheet::WriteExcel does the trick for me.
