After plenty of Googling, I could find no easy way of importing content (news articles and links) from a Joomla install in to a new WordPress install. The closest I came across was
Mambo2WordPress (direct download), but the original author’s page has been removed, so I could no longer tell if it was being maintained.

It was late, I needed it done, Google was failing me, so I took that chap’s script and modified it to work with recent Joomla & WordPress installs and then added some!

No support is provided, and you’re free to do with this script as you wish (be nice and leave the notice/credits intact).

Download

Download: Joomla2WordPress v1.0 zip file (~6KB).

Installation

From the enclosed readme.txt:

Installation
============
+ Unzip the downloaded zip file in your WordPress install
directory, and this will create a new joomla2wordpress directory.
+ In that new directory, edit config.php and supply the details
for the Joomla and WordPress databases.
+ Visit that new folder in your browser, and follow the instructions.
I.e. If your blog URL is http://www.myblog.com/wordpress/, then visit
http://www.myblog.com/wordpress/joomla2wordpress/ and follow instructions.
