How to prevent Ansible from re-ordering JSON?

Question

Given the following playbook fetching some data from some random webservice:

---
- name: sorting json
  hosts: localhost
  tasks:
   - name:
     uri:
       url: http://jsonplaceholder.typicode.com/users
       method: GET
       return_content: yes
     register: result
     ignore_errors: yes


   - debug: msg="{{result.content}}"

Ansible is reordering the json output:

Output (first element of array, reordered):

    {
        "address": {
            "city": "Gwenborough",
            "geo": {
                "lat": "-37.3159",
                "lng": "81.1496"
            },
            "street": "Kulas Light",
            "suite": "Apt. 556",
            "zipcode": "92998-3874"
        },
        "company": {
            "bs": "harness real-time e-markets",
            "catchPhrase": "Multi-layered client-server neural-net",
            "name": "Romaguera-Crona"
        },
        "email": "Sincere@april.biz",
        "id": 1,
        "name": "Leanne Graham",
        "phone": "1-770-736-8031 x56442",
        "username": "Bret",
        "website": "hildegard.org"
    },

Whereas the original data is:

 {
    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    "email": "Sincere@april.biz",
    "address": {
      "street": "Kulas Light",
      "suite": "Apt. 556",
      "city": "Gwenborough",
      "zipcode": "92998-3874",
      "geo": {
        "lat": "-37.3159",
        "lng": "81.1496"
      }
    },
    "phone": "1-770-736-8031 x56442",
    "website": "hildegard.org",
    "company": {
      "name": "Romaguera-Crona",
      "catchPhrase": "Multi-layered client-server neural-net",
      "bs": "harness real-time e-markets"
    }
  }

How to get a nice, formatted JSON which is not reordered? ( I have seen this question, it would still be nice if it was possible )

Answer 1

The value of result.content is not altered by Ansible and matches API response.

You can easily test it with:

- copy:
    content: "{{ result.content | string }}"
    dest: /tmp/raw.json

But when you use {{ result.content }} to display the value, you trigger Ansible type detection mechanism, which converts JSON string into object (which is unordered) and then prints the object's value (not original value).

To prevent type detection, you can use | string filter.
