I don't think JMP has any translation capabilities like that but you could do this with some translation API service and write a script to perform the translation (or you could use Formula but do not let it evaluate more than once). You might be able to perform the translation for example in Word (or something similar) and then move the data back to JMP. Also depending on your data, it is always good to be careful on which service you use if the data should not be shared / moved outside of your country.
