Longtail dynamic content with Squarespace

Hi community, 

I am planning to build out content pages for long-tail search terms like "Help with XYZ in Place XYZ". 

I'm looking for an easy way to create a lot of such pages with little effort. E.g. by uploading a spreadsheet with the data. Instead of having to create a ton of pages manually in the frontend. 

I was wondering if there is any good way of achieving this? E.g. by using code-blocks that allow me to implement content from a headless cms or is there any other good way of doing that?

Thanks for your support, 

Marvin
