How to split a string into rows of each character without Java Snippet

I am currently solving Advent of Code 2020 for learning KNIME.

On day 6, I want to split a string into rows of each character and have found a way to do this using Java Snippet. Is there any other way to do this?

Also, any other workflows for AoC 2020?

My workflow is on KNIME Community Hub.
