How To Parse JSON Data To A Human Readable Format [SOLVED] (lemmy.world)

So, yes this is selfhosting related. I am working on an n8n flow to pull in weather data so that I can have this data on a dashboard. I can't find any dockerized weather forecasting apps. Most of them connect to a personal weather station, which might be an option in the future. For the time being, this is a little project I'm working on.

Partial JSON snippet:

0	
json	
cod	"200"
message	0
cnt	40
list	
0	
dt	1780693200
main	
temp	29.4
feels_like	29.23
temp_min	29.4
temp_max	29.68
pressure	1019
sea_level	1019
grnd_level	984
humidity	42
temp_kf	-0.28
weather

I would like to display something like this:

spoiler

Current temperature: 23.25 °C
Feels like: 24.09 °C
Low / High: 23.25 °C / 23.60 °C
Humidity: 94%
Atmospheric pressure: 1023 hPa (sea level: 1023 hPa, ground level: 988 hPa)
Temperature correction factor (temp_kf): -0.35

Weather: Light rain
Weather code: 500
Short condition: Rain
Icon: 10d

So, this is for you devs or coders out there. I can produce the JSON data. I'm just not sure how to parse it to something meaningful. I'm sure Python will have to be incorporated, but unsure of how to proceed.

Maybe someone could point me in a direction to tuts, articles, or your own experience. Sorry the JSON data doesn't format correctly. Lemmy formatting doesn't seem to allow that.

ETA: For anyone wandering across this, here is the solution: https://lemmy.world/post/47961985/24201369 thanks to @captcha_incorrect for his generosity and time.

envsubst sed

Ahh more to explore. Thanks.

your requirements aren’t very clear on what you want this data for or how it will be used.

Apologies. As per usual, it's all in my head and sometimes doesn't make it to paper. I am using Homarr dashboard. Homarr has the ability to incorporate iframes. Ideally I would like to parse the JSON data into a prettier format perhaps adding some icons in the future once I get it all hammered out, and display it in an iframe on my dashboard.

Thank you for the leads and your time.

I don't know much about homarr but it sounds like going with jq and envsubst might give you a faster solution that you can just iframe in your dashboard. though the learning curve can be steep if you're unfamiliar with Linux command line.

I'm pretty sure you can literally pass in base64 encoded HTML to an iframe it will load in or pass it a publicly accessible file and it will work too.

I had messed around with building a locally hosted dashboard using similar methods so I'm pretty sure it will work.
