This code will get the text value from a Dynamic field and copy it over to a second field. Replace 125 with the ID of the field to change and replace 120 with the ID of the Dynamic field to copy. If you want to copy the value from a Dynamic list field, change 20 to the ID of the Dynamic field that the Dynamic List field depends on. Replace 50 with the ID of the linked field that the Dynamic field loads entries from.

This example will prevent paragraphs fields (and other fields that may have line breaks in them) from being fragmented when being imported as an .csv file.
