I'm trying to get some local weather data out of a JSON-file. If i had any hair when i started this it would be gone by now. It's so frustrating, but i can not seem to get my head around this. I read all about here at the stack, but i'm still stuck. No i'm trying to use XSuperObject but so far i have not succeeded in dissecting this, so please help me to understand. I have a lot of code from trying this, but i will provide my last attempt. Enclosed is also part of the JSON file, but it should be complete as it is. The rest of the files is just a lots of more "TimeSeries". My small test application is a form with a TMEmo for the JSON text and a TListBox for the result strings. Please can anyone set me on the right track to understand this JSON? How can i get to inner part of this structure? Thanks!

for itm in arr do

The mistake is that
timeseriesis an array, notdetails:
