shortcode testimonials as slider or import them into advanced layout builder

Hello,
I would like to display testimonials on company (about us) page as a slider element. That page is using advanced layout builder. However, I have a lot of testimonials and they are all currently in jetpack testimonials. I prefer not to manually enter them.
1. Is there a tool to import them and later export if needed?
2. Is there a way to use the short code option, BUT display them as a slider, not in list view? Maybe the testimonial element nested in a slider somehow?
3. We are starting to get testimonials directly on google (for better search results), is there a way to get those into that same slider automatically?
