I already built a single WordPress page template that contains the {{city}} placeholder and all the design/content I need. A CSV with 400 city names and preferred slugs is ready to go. What I need is for you to take that file, set up WP All Import (plus the small PHP snippets the plugin allows), and run the import so the site ends up with 400 fully-published pages—each one automatically replacing {{city}} with its correct value. The template is finished, so no extra edits or styling are required. I simply want the import process handled from start to finish: configure WP All Import, map the columns, add any necessary shortcode/snippet logic, run the import, and make sure every page is live and reachable with the right permalink. Once done, I’ll log in and spot-check a few cities; if everything lines up, the task is complete.
