The LinkedIn export includes stuff you probably don’t want to include for someone viewing your CV outside of LinkedIn. There isn’t a way to customize it, which is why there are so many tools for doing so.
Nobody reads past the first page anyway. I throw it all in. I landed jobs at Google and at several other high-ticket places with a LinkedIn-generated resume, FWIW.
There are lots of people in the world who could get high paying jobs without any CV at all. But that doesn't mean that the CV wouldn't matter for the rest of us.
