Putting one word per line

Hello,
I have a word list file that has three words per line. For example:
Arapaho: Arapahoes Arapahos
I would like to put each word on it's own line, like:
Arapaho:
Arapahoes
Arapahos

How do I do this quickly?
Can I use Frontpage to do this?

Thanks for your help.

Open it in dreamweaver (or frontpage i suppose, though i'm not certain if it will work) and do a search and replace find " " replace with
"
"

 

Thanks for your answer.
Are you the Andy Peters?

Unfortunately it doesn't work in frontpage, and I don't have Dreamweaver.
Any other idea for frontpage?

 

Ok, I've done it using something similar with search and replace.
Thanks.
