Hi @KainLittleCloth ,

You can use the Cell Replacer to do this. The Cell Replacer allows you to replace based on a dictionary/mapper.

The challenge is to replace multiple “words” in the same cell. You can break them down by playing around with GroupBy/Ungroup.

Something like this will work:

For this particular case, I would recommend to look at example below

Dictionary tagger could be skipped and String manipulation node needs to be added to replace comas by spaces.
Just 5 nodes to get result.


@izaychik63 @elsamuel Thankyou so much for your reply!! But I don’t have knime extension so i couldn’t use one of the node stated in your solutions…

But managed to the get solution proposed by @bruno29a !! Thankyou very much for your help!!!

To get extension installed, download example and open (double-click) it in KNIME. KNIME will ask you if you want to install missing extension. Good luck.
