{:ok, puzzle_input} =
  KinoAOC.download_puzzle("2015", "12", System.fetch_env!("LB_SESSION"))

My answer

puzzle_input
|> String.split("\n")
|> Enum.map(fn row -> Jason.decode!(row) end)

defmodule SumIntegers do
  def sum_integers(data) when is_integer(data), do: data

  def sum_integers(data) when is_map(data) do
    data
    |> Map.values()
    |> Enum.map(&sum_integers/1)
    |> Enum.sum()
  end

  def sum_integers(data) when is_list(data) do
    data
    |> Enum.map(&sum_integers/1)
    |> Enum.sum()
  end

  def sum_integers(_data), do: 0
end
