Create multiple pages with tables from json file

I have this problem on Wordpress. I have a json file with a structure like this

{ 
   obj: [ 
      obj1: {
         field1: ..,
         field2: [
            {
                field: 
            }
         ] 
      }, 
      obj2: {
       field1: ..,
         field2: [
            {
                field: 
            }
         ] 
     }, 
      ... 
   ]
} 

Now I need to create a page for each obj in the json by using Wordpress Rest API. I know I can do it, but the problem is that in each page I need to put a table populated with some field of each obj. I can create a page, but I don't know how to put table in that page.

Someone can help me? Thanks.
