Column headers to row values

Hello partners!! : D

Today I’m facing a new challenge in a knime workflow :muscle::smirk_cat:.

So, I was wondering if there is a way to convert column headers into values. Let me show you the table I have:

And the output I´m trying to get should be something like this:

OR

I need to sort those column headers as values, to find a time difference once it´s ordenated

The things I´ve tried are

• Unpivot

• Column agregation + ungroup

• List column group + date & time difference

Some of this solutions lose data, create “duplicates” or simply didn’t work

I ran out of ideas, so I´ll be very happy with any new idea or help to this.
