Import HTML Topic without formatting/tags

I am re-writing a previously created RoboHelp project using RoboHelp HTML 11.  For many of the pages, I want to start with the original page so I choose the Import HTML File option. That works fine, but they have hardcoded fonts and formatting that I do not want. Is there any way to import the page and strip out the formatting?  Sure, I can do all this manually, but I have a lot of pages to import!
