I guess you mean "newline" and not "next line".
Why an additional step in between ? Why not replace newlines with 100 spaces directly ?

Again, why substitute by the "." first ?

If directly we can do it, it will be great. Can you please send me the command.

Do you want to replace the last character with 100 spaces?

Code:
cat fichero | sed "s/$/`perl -e 'print \" \" x 100'`/"

Or using just Perl:

Code:
$
$ cat space
asd
fghj
itkg
$
$ perl -ne '$x = " "x10; s/\n/$x/g; print' space
asd          fghj          itkg          $
$
$

Replace 10 by 100 in the one-liner above.

Code:
perl -e ' while (<>) { print $_ ," "x100;} ' filename
