N8n data manipulation

Describe the problem/error/question

I can’t parse the nested list to use each item as input for another module.
I have a module that generates a variety of things, including a checklist for tasks. The number of tasks will depend on the initial task, so it will always be a different amount. Each time I create such a checklist, I would like to get each item and use it for the Trello add checklist item module.
I find the problem with proper parsing tasks, and getting the LoopOverItems loop amount depended on the amount of tasks.

And this is how the data I want to use looks like:


"Rozbicie_Zadania_na_Kroki": 
[
{
"krok": 
1,
"opis": 
"Przygotowanie danych: zbierz podstawowe informacje o działaniach podjętych w minionym tygodniu.",
"szacowany_czas": 
"30 minut"
},
{
"krok": 
2,
"opis": 
"Przeanalizuj osiągnięcia, napotkane trudności oraz obszary wymagające poprawy.",
"szacowany_czas": 
"20 minut"
},
{
"krok": 
3,
"opis": 
"Opracuj wnioski i propozycje działań do wdrożenia w nadchodzącym tygodniu.",
"szacowany_czas": 
"30 minut"
}
],

Desired output is that each
Each task (opis) and each time (szacowany_czas), will be inputed into the Trello add checklist item module seperately.

Hey @rafal_radzi
:wave: welcome to the n8n community!

I tried to re-create your use case and cam up with this demo workflow:

If I got it right you need to add all the tasks in the original JSON as checklist items in Trello
This demo workflow should do that.
The only thing it doesn’t do is select the right Trello card (as I didn’t find where that info is coming from)

Let me know if this helps!
