You could do something like this

- set_fact:
profiles_dicts: |
{% set res = [] -%}
{% for key, value in ansible_local.was.profiles.iteritems() -%}
{% set ignored = res.extend([{'Server': key,
'ENV':value.env}]) -%}
{%- endfor %}
{{ res }}

Its not clear to me exactly what you want the result to be after your set_fact processing but I suggest you take a look at json_query plugin as you might be able to use this to just pick out the bits of the result that you need.  See http://docs.ansible.com/ansible/latest/playbooks_filters.html#json-query-filter  

One of the nice things about json_query is you can use the JMESPath examples page here: http://jmespath.org/examples.html to try out your queries (just paste your json into an input box and tinker with the query until you get results you need.

Hope this helps,

Jon

Hi guys

Output:

{

    "profiles_dicts": [

        {

            "ENV": "env",

            "Server": "epn-was8-dmgr-trn"

        },

        {

            "ENV": "env",

            "Server": "epn-was8-node-trn-01"

        },

        {

            "ENV": "env",

            "Server": "epn-was8-node-ppe-01"

        },

        {

            "ENV": "env",

            "Server": "epn-was8-dmgr-ppe"

        }

Is it possible to change my loop in order for my output to be ENV to match PPE or TRN and not env?

I am not sure how to achieve this
