generate 2 line from 1 lines

how can I achieve this transformation please,

Hi @mosmel, glad you managed to find the result you needed. Just in case somebody in future has a need to do something similar, it would be good (if you are able) to actually upload an export of your demo workflow, as a picture of the nodes used only tells us part of the story. Without being able to see what each of those nodes is doing it is a bit like having a “recipe” for a cake, which only includes the ingredients and a photo of the finished cake. :wink: thanks.
