Urls from a converted Joomla to WordPress

Hello

This weekend I converted a website from Joomla to WordPress
the convert went well without problems and all the content
that I need is now in wordpress.

The only problem that I have is that Joomla Seo links
looked like https://www.domain.com/mylink.html

and the Seo links in wordpress look like https://www.domain.com/mylink

without the html at the end

is there anyway that I can get wordpress to recognize the old links and still goto the right page.

I dont know if you could do something in the wordpress .htaccess file
like a 301 redirect and list all the links or there is any easy trick
with mode rewrite

any advice would be most greatfull
