Data Import in Contact Object using a custom field
I need to use Data Import in Contact Object using a custom field as the lookup ( no contact id to be used in data import) and update another custom field .
I will be having data in CSV with columns : Custom field 1 (this is indexed & will contain unique ids but it wont be Contact Id) , Custom field 2(this value needs to be updated in the contact object) . Is it possible to do so ?
Do I need to extract Contact id using that Custom field 1 and then use the contact id as lookup in the contacts and update value of Custom field 2 ?
