why it doesnt read and put the points as X Y Z
Try deleting and replacing your file selection node. I’m not sure why it happens but I’ve had that node go corrupt or something in the past. Replacing will sometimes fix it.
Try using at get item at index node instead of the code block at the second to last node on the right.
Edit: use list at level 2 for the get item at index node. You will need three get item at index nodes to replace that one code block.
The read from excel Node requires a Boolean value for the ReadAsString input, not a string one.
Also it looks like you are missing a few years worth of updates - what Dynamo version are you on?
