I looked at your exporter for migrating my personal website.
Like most other exporters, it gets the basics right but misses out on a lot of subtle features listed here https://github.com/ashishb/wp2hugo#goals-of-wp2hugo
I successfully exported small blogs using the wordpress-to-hugo-exporter plugin, but it times out on big blogs, even increasing max PHP runtime for scripts to several hours. I had no choice but to rely on an offline, desktop variant and wp2hugo is super fast.
