The export to text file, how do you do it?

There may be several ways to go, here is one using Regular Expression.

$regexp('Author 1, Author 2','^(.+),\s(.+)$','$1 and $2')
==> 'Author 1 and Author 2'

$regexp('Author 1, Author 2, Author 3','^(.+),\s(.+)$','$1 and $2')
==> 'Author 1, Author 2 and Author 3
