Creating an array

[Linuski]

I have this kind of json:
{ "entities": {
"organisations": [
{ "id": "b9c0b61b-e843-48c8-83a2-52bf2ea00971", "label": "ReCAAP ISC" }, ... other things ],
"places": [
{ "id": "97fe568b-5b25-46dc-bb85-0a7f52996f1d", "label": "Bangladesh" }, ... other things ]
}
}

I would like to have this:
[
{ "id": "b9c0b61b-e843-48c8-83a2-52bf2ea00971", "label": "ReCAAP ISC" },
{ "id": "97fe568b-5b25-46dc-bb85-0a7f52996f1d", "label": "Bangladesh" }
]

I used this transformation:
[{
"operation": "shift",
"spec": {
"entities": {
"places": {
"": "R0[#2]"
},
"organisations": {
"": "R0[#2]"
}
}
}
}, {
"operation": "shift",
"spec": {
"R0": { "*": "" }
}
}
]

which works well for thsi case but when I have this other case:
{ "entities": {
"organisations": [
{ "id": "b9c0b61b-e843-48c8-83a2-52bf2ea00971", "label": "ReCAAP ISC" } ]
}
}
the result is not an array:
{
"id": "b9c0b61b-e843-48c8-83a2-52bf2ea00971", "label": "ReCAAP ISC" }
}
How can I fix this?

Does this specification cover all cases?

[
  {
    "operation": "shift",
    "spec": {
      "entities": {
        "organisations|places": {
          "*": {
            "id|label": "&2.&1.&"
          }
        }
      }
    }
  },
  {
    "operation": "shift",
    "spec": {
      "*": {
        "*": "[]"
      }
    }
  }
]
