Importing via csv creating duplicate phone end email fields

[riswana123]

Hi,

  If i am updating the contacts via csv and mapping the work details(address,phone,email) with work and home details(address,phone,email) with home and selecting these two options for duplicate contacts its creating multiple phone and email fields.
1. UPDATE
2. NO DUPLICATE CHECKING
Can anyone please clarify?

2. NO DUPLICATE CHECKING

That is your problem.    Read the documentation on import settings.  What this setting means is that you are telling CiviCRM not to check for a matching contact and thus it always creates a duplicate as you have instructed.

A better setting would be to match on: email + name, or external ID number (from your legacy database) and update the matching contact.   You can choose the dedupe rule you wish to use.
