Since you mention Excel I am assuming you are using a PC or Mac
platform.  One very flexible solution would be to install an
AWK interpreter and use a simple AWK script to select the
lines you require.  For the PC I use GNU's GAWK and for the
Mac, MacGAWK.
     AWK is a very simple and flexible file processing language
and is ideally suited to this task.  If you choose to go this
route I can send you an AWK script for the purpose - or if you
want it done properly post the question to comp.lang.awk
where you will, I am sure, receive many informative replies.
     Other possibilities are to use Perl (in a similar manner
to AWK) or to bring the file into your favourite word processor
where you can write a macro/script/whatever for copying every
n'th line to another document.
     I hope that this helps,
          Bernard
