Trying to remove the extension from a list of domains

[rupert]

I'm looking to convert a list of domains into just a list of keywords.

By that I mean, rather than having a list like this:

domain1.com
domain2.com
domain3.com
domain4.com
domain5.com
etc

I'd like to have a list like this:

domain1
domain2
domain3
domain4
domain5
etc

Do you know of any online tools or tricks that I could use to do this?
There's around 40,000 domains in the list so I don't want to have to do it manually.

Thanks.

Open the list in notepad or ooWriter or word.

Use the 'find and replace' function to turn .com into nothing.

Good Luck!
