How to replace single characters in a Excel column using a dictionary of key-value pairs?

Hi @fryfella,

welcome to the KNIME community!

I would suggest to use a recursive loop. You can find an example with a small dictionary replacing some special characters in German language on the KNIME Hub:

To get familiar with recursive loops I recommend the following video:
