Change the date format of the output report

It looks like from your images that you are actually trying to format Excel and not KNIME. There are 2 ways of doing this. I will link to a previous forum answer that I had about formatting percentages. The options / process for formatting Dates in Excel files that are written from KNIME are the same.

Column type to percent in excel

I think he just means to display it as a percent in Excel when it is written. There are 2 approaches. You can either format an excel “template” and then write your values to it using this… (Template just means an existing file, so you can write / format in excel, then use that as the formatting template for future changes.) Or format the excel file using a series of Continental XLS formatting nodes.
