Migrate 600 blogs and bulk convert them to BeaverBuilder posts

Hi all… glad to find this community.

I have 600 blogs from an old website (non Beaver Builder) that I want to migrate to a new Beaver Builder site. I can export and import them in WordPress of course.

But is there a bulk/programmatic way to turn them into Beaver Builder posts and ideally assign them a template (template is very simple… narrow width column, first row is a prebuilt component, last row is a prebuilt component, middle row is text from my imported post).

Any ideas out there? A bit stuck!
