Giving AI a large dataset with JSON

hey! i would like to ask how i could train a pre-existing LLM on a huge(and a very huge) JSON file that has a bunch of files/directories converted into json form. i want the LLM to be able to understand/process and remember all the data in the file.

here is the format of the JSON file.


{ 
  "src":
  {
    "platform2":
    {
      "init":
      { 
        "startup":
        {
          "chrome_startup_text.txt":
          {
            "type": "txt",
            "content": "{text here seperated by \n}"
          },
          "chrome_startup.txt":
          {
            "type": "txt",
            "content": "{text here seperated by \n}"
          }
        }
      }
    }
  }
}
