.htaccess Redirection - Regex for *.html to wordpress urls

Question

I've moved a static site (*.html) to wordpress with no changes to the urls.

Example:

domain.com/sample-url.html to

domain.com/sample-url/

There are over 200 pages and I'm tired of setting up redirection for each page. Is there a regex to put it on .htaccess file to fix this issue?

Thanks in advance.
