I am using the networktocode ntc-ansible module in Ansible to control Cisco IOS devices (switches currently). I successfully can use ntc_show_Command to get 'show version' and 'show ip int brief' and put the result into a local file. But when I use the -vvv at the end of the ansible-playbook command, I see structured JSON output in the terminal. How do I get a access the "module_args" and the "response" from the ntc_show_command, ie. if i use "show ip int brief" and i want to know the status of int gi1/0/5. How can I access that? And then... what playbook commands would/could I use to grab the specific data I am looking for?
Here is the output I can see when I run the playbook, with -vvv, but I don't know how to access the structured data

Here is the output of the Show ip int brief in the local file.
Interface IP-Address OK? Method Status

Vlan1 172.16.x.xxx YES NVRAM administratively down down
Vlan2 192.168.x.xxx YES NVRAM up up
Vlan10 10.10.yy.xxx YES NVRAM administratively down down
Here is my play...

connection: ssh

UPDATE I updated code based on suggestions as such:
I made progress, but I seem to still be missing something important. My first debug statement (below) is outputting the full output (not shown here), which works. I can set_fact successfully to 'interfaces'. I can loop through the interfaces variable and detect a condition set with the when statement, which I changed to look for all up/up interfaces. BUT... my output (shown below doesn't show the details yours showed. Mine shows (item=None) for all and an OK on items which match the criteria, but not the details your output shows (your second code block in original answer).
UPDATED - I modified the debug var to 'item.intf' and now I get intf name, but still not all details.
**QUESTION: How can I grab an output that shows only the interfaces that meet the criteria? Can this structured data be saved to a file?
UPDATE 2:::
I was able to use the copy module to copy {{ interfaces }} to a file as structured data, but when I try to just show the interfaces, and not the rest of the data, but using {{ interfaces.intf }} I get an error. (See below)
Question: How can I get a output / file that shows only the interface names?
Question: How can I get an output / file that shows only the interfaces names that are up/up?
My second debug statement (below) is outputting this, which identifies the up/up interfaces: UPDATED.

ok: [VTgroup_SW] => (item=None) => {
"item.intf": "Vlan2"
