If you have a lot of files to do this to, I would suggest learning at
least a little bit of perl. It might not be as nice an option as a
python tab manager (depending on your point of view), though.
Perl uses regular expressions. In case you'd like to see how to do
your tab-space replacement, the following bit of code would convert
tabs to 4 spaces.
Take care,

#----------------------------------
use strict;
use warnings;
my $file = $ARGV[0];
open(IN,$file) or die $!;
open(OUT,">".$file."notab") or die $!;
while(<IN>){
$_ =~ s/\t/ /g;
print OUT $_;
}
close(IN);
close(OUT);
exit;
