GoDaddy Website Builder has no export tool. Not a partial one, not a paid one. There is no button, and there is no file at the end of it. Leaving means rebuilding, and the only question is how much of your content you rescue on the way out.
This is the same shape as Wix, with one difference that catches shop owners badly, below.
GoDaddy lets you import a product list. It does not let you export one.
If you run a shop, this is the single most expensive fact on this page, and almost nobody finds it out until the day they try to leave. Every product name, description, price, option and photograph has to be collected by hand or retyped somewhere else. Budget real hours for it, and do it while the store is still live.
You cannot install WordPress on a Website Builder plan. If someone has told you to "just switch to WordPress on GoDaddy," that means a different hosting product and a different bill, not a setting.
And a warning about the shortcut you will find online: site crawler tools such as HTTrack or wget can pull down the published pages. What you get back is machine generated markup wired to GoDaddy's own stylesheets and scripts. It is occasionally useful for recovering text you would otherwise retype. It is not a working site, and treating it as one is how people end up with something broken they cannot fix.
We do this for people. We rebuild the site properly, map every redirect before anything switches over, and your old site stays up until you tell us you are happy with the new one. From CA$1,800, quoted after we look at your pages rather than guessed. Tell us about your site.
