Json – Use jq to convert object to sorted array

I have the following JSON object.

{
  "1eba648810a9": {
    "ID": "1eba648810a9",
    "Tag": "1.0.237"
  },
  "2df272728204": {
    "ID": "2df272728204",
    "Tag": "1.0.243"
  },
  "2f5a63db6634": {
    "ID": "2f5a63db6634",
    "Tag": "1.0.179"
  },
  "91a86fec59b1": {
    "ID": "91a86fec59b1",
    "Tag": "1.0.202"
  },
  "9aa95de44891": {
    "ID": "9aa95de44891",
    "Tag": "1.0.189"
  },
  "a1caaccdba45": {
    "ID": "a1caaccdba45",
    "Tag": "1.0.183"
  },
  "a35ad9d93e62": {
    "ID": "a35ad9d93e62",
    "Tag": "1.0.42"
  },
  "a4e57f2db7eb": {
    "ID": "a4e57f2db7eb",
    "Tag": "1.0.181"
  },
  "d0254d6406e0": {
    "ID": "d0254d6406e0",
    "Tag": "1.0.253"
  },
  "ddeeb3d41a4c": {
    "ID": "ddeeb3d41a4c",
    "Tag": "1.0.177"
  },
  "f92356a49d78": {
    "ID": "f92356a49d78",
    "Tag": "1.0.178"
  }
}

How do I convert this into an array and sort it by Tag. In the end I want something like this.

[
  {
    "ID": "ddeeb3d41a4c",
    "Tag": "1.0.177"
  },
  {
    "ID": "f92356a49d78",
    "Tag": "1.0.178"
  },
  {
    "ID": "2f5a63db6634",
    "Tag": "1.0.179"
  },
  {
    "ID": "a4e57f2db7eb",
    "Tag": "1.0.181"
  },
  {
    "ID": "a1caaccdba45",
    "Tag": "1.0.183"
  },
  {
    "ID": "9aa95de44891",
    "Tag": "1.0.189"
  },
  {
    "ID": "91a86fec59b1",
    "Tag": "1.0.202"
  },
  {
    "ID": "1eba648810a9",
    "Tag": "1.0.237"
  },
  {
    "ID": "2df272728204",
    "Tag": "1.0.243"
  },
  {
    "ID": "d0254d6406e0",
    "Tag": "1.0.253"
  },
  {
    "ID": "a35ad9d93e62",
    "Tag": "1.0.42"
  }
]

Note that the sorting by version is not entirely correct but that’s a separate issue. Ideally, I would like a solution using only jq instead of other external tools.

The following question has been suggested as a duplicate but it’s not relevant because that is sorting an array, not an object.

    You would convert the object into an array with to_entries and map

    echo "$your_object" | jq 'to_entries | map(.value)'

    Sorting can then follow.

    Just iterate over the (outer) object’s items using .[], and collect them into a new array by surrounding with […]; or use map(.) with the same effect. The sorting can then be achieved using sort_by(.Tag).

    jq '[.[]] | sort_by(.Tag)' input.json
# or
jq 'map(.) | sort_by(.Tag)' input.json

    [
  {
    "ID": "ddeeb3d41a4c",
    "Tag": "1.0.177"
  },
  {
    "ID": "f92356a49d78",
    "Tag": "1.0.178"
