I would refer you back to this post, which you asked a similar question on. It does answer the question.
As @jorn mentions, how you go about it is complicated and depends on your skills and resources. If you wanted to export the data to another CMS, then that would depend on the CMS. If you wanted to create pages from CSV data, that would depend on either your database skills or knowledge of things like python.
I could give you a more specific recommendation if you could articulate why you would want to do this versus just using the webflow CMS with hosting.
