Redirecting all pages with .html extensions

Hello guys,

Please can you tell me if it is possible to set up a 301 redirect for all pages with .html extensions? The problem I am facing is this – my site was initially built within Weebly which added .html extensions to all pages. WordPress does not do this so I need to point the .html pages to the non .html pages now so as not to break all the links. I am currently using a plugin to append .html to the urls, but I do not believe this is the best issue from what I am reading. Every article mentions doing a 301 redirect in htacccess. Which leads me to my other issues – my host namecheap does not allow access to htacces (so htNOaccess in this case!), so I cannot implement the solutions I am reading about. Please can you tell me if I can achieve this with your plugin? I sincerely hope so. Thank you for your assistance.

Michael.
