Just found this useful keyword/text tool

okay, it's our tool but I think you can find it useful and I would appreciate your feedback.

http://textshaker.com/

you can convert keyword lists to URL slugs
add prefix or suffix to your lists
clear your list with whitelist and blacklist
sort and mix your lists
test your spintax or trim your scraped results

it also supports multiline search and replace

thanks,
Ivo
