Hi, @natsumimori The poster specifically asked if there is a way to “IMPORT” an excel document THAT contains a CONTACT ID and in order to mass update (import) an associated ID (and I think he means the Company he wants linked to the Contact). You provided a knowledge link and said it goes through how to import and associate records. Does this article answer the question? Maybe I’m missing something but I don’t see how to do this. Can you provide instructions?
