How to redirect old .html URLs to WordPress URLs ending with a slash like this/

I moved my blog from TypePad to WordPress. All my TypePad posts and pages ended in .html. The URLs looked like this:
https://myblog.com/weblog/2010/09/read-this.html.

Now on WordPress the URLs look like this:

https://myblog.com/weblog/2010/09/read-this/

The URLs end with a slash instead of .html.

I installed the plugin Broken Links, which shows all the links have broken.

How do I redirect all the .html links to /?

I downloaded the plugin Redirections but can’t figure out how to use it.

Please help. Thank you.
