How To Remove Duplicates And Clean Up Contents

in my sample xls,there are some contents (text) that i don't need. i'd like to remove the duplicate entries from the Consignee Address rows based on the contents of the Consignee City cells. what i mean? lets say, here,the word CHIOS shows 3 times,we dont need that,so we have to delete it in the Consignee Address,and leave it only in the Consignee City

Shipment Number Consignee Consignee Address Consignee ZipCode Consignee City Consignee PhonePieces Shipment Total Weight
0866-03636276 MRS NELLH NIRI LEAFOROS AIGAIIOU 22 CHIOS CHIOS 82100 CHIOS302023288 1 0.11

so,the final text should be like this:
Shipment Number Consignee Consignee AddressConsignee ZipCode Consignee City Consignee PhonePieces Shipment Total Weight
0866-03636276 MRS NELLH NIRI LEAFOROS AIGAIIOU 22 82100 CHIOS302023288 1 0.11

in the second case,we have something like this:
Shipment Number Consignee Consignee Address Consignee ZipCode Consignee City Consignee PhonePieces Shipment Total Weight
0866-03636453MRS KRISTINA L. KALIVION 252 LAMIA -- SELECT STATE -- GR 35100 -- SELECT STATE -- 6954689 1 0.43

here,we want to move the city (LAMIA) ,and replace the -- SELECT STATE -- in the to Consignee City
