For people who are OK with custom ansible modules: https://github.com/ParticleDecay/ansible-jsonpatch works great!

With this you can simply do:

- name: append key/values
  json_patch:
    src: /tmp/var.json
    operations:
      - op: add
        path: "/hello"
        value: "world"
    pretty: yes
    create: yes
