Flatten lists of lists @2nd level

can anyone help me solve this problem? i want to join the lists @2nd level.
i have for example 50 lists with 10 to 15 sublists, and i would like this to be 50 lists without sublists

If I understand correctly then you’d want to flatten @L3. EDIT: If I understood incorrectly then you’d want to listen to @khuzaimah.ElecEng.

If the lists are at L2 then they’d be grouped under L3. So you’d want to combine all the L2 lists in L3. This would retain the structure you already have at L3 and up but combine everything underneath it.

hi
use flatten node with "amt " value of “1”

Hi @l.dorrestijn ,

Try the node List.NormalizeDepth with a 2 as rank input.
This node works as the list.flatten node, but from the right side :smiley:
