Group loop start- could not sort with categories

[CCCCH]

Hi,

I’m trying out the group loo start node. But it wasn’t look like what I expected…
I have a table with different categories in one column. After the table creator, I use Group loop start to sort, but it shows ONLY one category in the table.
Any idead about this? How can I solve this?

Table creator:

Group loop start config:

Group loop start outcome:

Can you tell us more about the result you were expecting?

I don’t think there’s anything going wrong. You executed a loop start node, which is not followed by any processing nodes, and no loop end node. Therefore you got the results from the first iteration.

With your current setup, I can’t see that result changing.

Here is the wrokflow i made. I was expecting to get spread sheet with each category.
But it shows only one categy with one spread sheet in the final out come.

Hi @CCCCH

Your excel contains only the last group. To write an file for every group, you need to make the path/name dynamic. Although this wf by @elsamuel from the KNIME Hub uses a different loop and a csv writer, it is a good example how to fix your problem. Excel to CSV Loop – KNIME Community Hub .
