This workflow shows how to filter out columns with at least one NaN value in their rows. The workflow answers the question asked by Vani_26 in forum thread number 62126. The workflow achieves the task by converting first the NaN values into Missing Values and then using a -Missing Value Column Filter- node to filter out columns with Missing Values.
