Creating pages from Ninja form data

I've created a WordPress page with a Ninja form on it that collects miscellaneous data about a product, including some uploaded images. The page with the form is accessible from the main menu by clicking the "Input" item, so the user doesn't need to access the backend to upload their product data.

I now want to put this data into a custom post type called "listing." There will eventually be thousands of these data sets and so thousands of "listing" pages, as people come to the site, click Input in the main menu to get to the page with the Ninja form and fill it out.

Could someone tell me how they would go about now building these listing pages from the data the form has collected?

Someone mentioned that the Front-End Post option of Ninja would create a new page for me from the data but after installing Front-End Post and Front-End Editor I haven't seen this option.

Thanks for your help.
