import of pages being created with xml or csv in wordpress

There are 30 pages i have already created with images , text etc showing hotels and attractions activities on a spesific state . I need to import new pages in wordpress showing exact the same content like the 30 ones (clones) but new ones will change some data in their content . For example a ready page Has title " Hotels in athens " , data for listings "athens" , meta data word "athens" url : [login to view URL] image /stories/[login to view URL] , <h3> ... Athens .. </h3> etc... The new pages that will be created will be exact the same page but instead of the word Athens ti will change for example to "rome" . So all content in the new pages will change to " Hotels in rome " , data for listings "rome " , meta data in yoast word "rome" url : [login to view URL] image /stories/[login to view URL] <h3> ... Rome.. </h3> etc . next page " Hotels in Paris" , data for listings "Paris" , meta data word "Paris" url : [login to view URL] image /stories/[login to view URL] <h3> ... Paris.. </h3> etc. There may be another page from the 30 ones that is not for hotels but for museums , so the first example content of that page will be like " Museams in Athens" , data for listings "Athens" , meta data word "Athens" url : [login to view URL] etc and will be changed to " Museams in "Pome" , data for listings "rome " , meta data word "rome" url : [login to view URL] <h3> ... Rome.. </h3> etc if the freelancer exports in xml or csv the data of one of the 30 pages and edit the content , if he searches and replace the state "athens" with another state (2700 will be provided) the xml is almost ready, only the name of state changes in every page everywhere . here is a real example [login to view URL] . and the result with manual edit [login to view URL] , its the same page cloned with diffefent state "italy" everywhere inside, The pages can be imported with wp all import pro (already installed) (check more here [login to view URL] ) or however you want and will be finally about 70-80 k new pages created , freelancer can export any data he needs , (i have installed wp all export pro), i will provide xls with about 2700 states. Then he will schedule to import all new pages
