We are pleased to announce the availability of lj2wp, a toolkit that allows you to export LiveJournal posts and import them into WordPress in an isolated environment.
The current WordPress LiveJournal importer was broken as of 2017-04-09, but an older path exists that can enable you to import your LiveJournal to WordPress.
The tool ljdump still works to export LiveJournal content. It contains a converter called
convertdump that exports that to an older WordPress XML import format. Unfortunately, WordPress.com and recent versions of WordPress no longer import this format. In order to import it, you need an older version of WordPress, sucn as 2.7.1. If you have that on hand, you can go through the process described in lj2wp to get a Wordpress-formatted import file you can use in a modern version of WordPress, or other software that can read WordPress export files.
I used this myself to migrate my LiveJournal account to wordpress in 2017. In April 2019, I secured permission from both of the authors of the upstream code to relicense this under the MIT License with an Obscure Organization copyright.
