I am using Mautic Version 3.2.0 and importing the contacts from the CSV File. I have created some custom fields in mautic that need to be populated with data after calculating some other fields. For instance, ‘lead\_age’ is a field that should be filled with age value result obtained from the calculations on ‘lead\_birthdate’ field.

Any suggestive help, clues, or link to guides that address this issue would be greatly appreciated. Thank you! 🙂

You can put the value calculated for ‘lead\_age’ field, and the value will be calculation of ‘current date - lead\_birthdate’ and then import on mautic, the data will successfully popped out.
