i have around 5k leads in my database with "junk" country names which i can't get rid of by data value change, b/c Marketo does not allow me to substitute an old value with a new "empty" one
is there a way to substitute country name with inferred country value?
In addition to Breno's suggestion, if you have a need to blank out a field, this can be done by using a Change Data Value step, and setting the New Value to "NULL". This will empty the field of all values.
