Typo3 to WordPress

I am planing to change the CMS of my website from Typo3 to WordPress. I have over 500 articles and it would mean days or weeks to me to recreate all those articles manually.

Two questions:
1. Is there a way I could export the articles/sites from Typo3 and import them into WordPress automatically?
2. What do I need to note if I want to rebuild the same theme? Can I just copy/paste the CSS or are there going to be any conflicts? I know how to create themes and plugins on WordPress but I don’t know anything about Typo3.
