Change Excel Datasheet format

Hi there,

I’m completely new to KNIME and have a question: I have an Excel Datasheet which contains all of my information seperated by comma in just one column. The first row contains all the headings for the respective columns I want to generate. How can I generate a datasheet with more than one column? Is there a way to display the newly generated Excel table to see if I have worked correctly?

Thanks in advance & greetings

Marina
