The short answer is no. Most of the page builders (of any kind) are designed to get information INTO the site and not out. Consequently, there are few if any tools for automagically moving a non-WP site into WP.
Unfortunately, copy/paste does not always work easily because sometimes html code is copied as well and the formatting becomes a bit jumbled.
When I've done this, I typically use a text editor (Notepad ++) to copy the orignal content and then end up pasting into wp. If you have quite a few pages, you might consider doing a "post/page" import. You will need to learn just a bit about the fields that WP would require for your import.
You will also need to save your images locally and then upload them into wp. Not a difficult process by any means, but can be quite time-consuming.
For me, the key to moving from non-wp to wp is taking some time to plan the move. Find out what content has to come across first and get that together. Get all of you images together BEFORE you start. Define the functionality for your site so you get the right plugins from the start. While these types of migrations are a pain in the @#%, they often result in a much more functional tool.

@JMPepper same question for Go Central. Can i move a Business Website builder into Go Central. I started with something way too simple for me need more options. I can do WP or GC but would rather not have to rebuild my site AGAIN.
I did that originally when i came to GDaddy. Full Dreamweaver site of 20 years dropping down to WB was a little fisher price for me but i wanted the simplicity. I was told it was responsive to but found out after the fact it was not. GC and WP are so would like to move to one of those.
Please advise. Thanks
Starting over with WP is going to be a bit of a pain but do-able. How many pages do you have to convert?
Basically, I do a couple of things to prepare.
Currently I'm using the Beaver Builder theme/child theme and the ultimate plugin package. Its turning out to be pretty potent in terms of quick development and ease of use. Paying a little bit for the ultimate add-ons has been worth every penny!
If you are brand new to WP, take some time for education! -- One of my favorite places is WPMUDev. https://premium.wpmudev.org/academy/
