This is functionally equivalent to what you've written, which was:

$data =~ s/\n/\\n/g;
$data =~ s/"/\\"/g;
$data =~ tr/\cM//d;

By using 'for $data', $data gets aliased to $_ which is the default
variable that s/// and tr/// act upon. By using 'for' as a
statement-modifier (that is: in postfix notation) no block is needed
which would normally be the case if you wrote:

for ($data) {
s/\n/\\n/g;
s/"/\\"/g;
tr/\cM//d;
}
