A “no-code” alternative to the String Manipulation could be to use a “Cell Splitter By position” node with the following config
which tells it to split into two columns “X-Discard” and “Appendix” at position 6, so the first 6 characters go into the first column (which we will be discarding, hence the name I chose) and the remainder into “Appendix”.
You would then add a column filter to remove the unwanted “X-Discard” column.
