How to sort songs according to lyrics?

I'm going to DJ at a party, but its a party where songs with explicit
(swear word) lyrics wouldn't be socially acceptable. All of my iTunes
songs have lyrics, but I don't know how to make a separate "clean" (no
swear words) playlist with songs that don't have any explicit lyrics.
I looked it up, but all I found is a "script" or whatever for iTunes,
and I don't know how to use it. So no scripts please! But thanks for
the help!
