Is an example of a json with 2 Primers and their location. This could be easier to read with keys for example something like.

[
  {
    "primer": {
      "volume": 5,
      "english": "A",
      "alBhed": "C"
    },
    "locations": [
      {
        "_area": "Another",
        "_section": null
      },
      {
        "_area": "Test",
        "_section": null
      }
    ]
  },
  {
    "primer": {
      "volume": 6,
      "english": "C",
      "alBhed": "D"
    },
    "locations": [
      {
        "_area": "Another",
        "_section": null
      }
    ]
  }
