Can anyone point me in the right direction for a drop editor that handles Json drops like the ones below? This is from Morytania Source

Code:
[
{
  "npcIds": [
    100,
    101,
    102
  ],
  "drops": [
    {
      "id": 526,
      "count": [
        1
      ],
      "chance": 0
    },
    {
      "id": 25,
      "count": [
        1
      ],
      "chance": 4
    },
    {
      "id": 25,
      "count": [
        2
      ],
      "chance": 4
    },
    {
      "id": 25,
      "count": [
        3
      ],
      "chance": 6
    },
