Hi all, Struggling with lists again, is there a way to match these lists with sublists in the following way?: [imagen] List 0 List [0] RV1 insertar descripcion [1] null [2] null [3] RV2 insertar descripcion [4] null [5] null [6] RV3 insertar descripción [7] null [8] null [9] null 1 L…

@DyNewby Your welcome. the c input was just a space so the words wont connect. Wy this fails is because your input in IN[1] is a list of 60 items. You only need your 10 items. So the input should be a flatten list with: 1 RV1 Insertar Descreipcion 2 RV2 Insertar Descreipicion 4 RV3 Insertar Desc…

@DyNewby I mead a example for you. I think this is what want to do. I hope I helped you. [Exemple]

Hi again @Yna_Db , I know it looked I haven´t done my homework, but I honestly couldn´t figure it out, I was always running into the same issue, the prefix was following the index and going up! I can´t get ride of the null values because I would like to keep the spaces in the excel table I want to cr…

Thanks again @Yna_Db ! Well, I have tried some attempts to adapt your reasoning, but if you don´t mind, can I ask what would be your approach to deal with sublists? I have tried flatten it but it is not working as it keeps numbering sequentially, and getting every item at index option sounds good to …

Thank you soooooooooo much @NLDaniel ! No words for such a neat solution! Love it! If you have another minute to spare, would you be so kind to tell me what am I doing wrong? Not sure what you connected to c, but I´m not getting the same results. [imagen]

You will need to use List@Level for that, please see here how this works: http://dynamoprimer.com/en/06_Designing-with-Lists/6-3_lists-of-lists.html The Dynamo Primer is a useful resource in many cases, but for now: [Sublists-replace-items]

Oh, I´m so sorry to make a fantastic user not complain with the guidelines, but I´m so sure he did it with the best of intentions in mind. I´m definitely not an advanced user, not even an intermediate one, but after seeing tons of examples I could guess some approaches, and it looked like that with …

It seems that the OOTB nodes can’t do this easily. These ones could help:
