Filter Columns After Cell Splitter

Hi everyone, I am trying to use the Column Filter node after using the Cell Splitter node. I am using this expression: NAME|MONTH|ID_Arr[1]_Arr[0]

But I cannot include the column ID_Arr[1]_Arr[0]

Thank you

Hi @salazachou

Since you are using Regex, you need to escape the brackets since their purpose in this case is not to define a group.



Thank you it worked perfectly.
