Moving outlook contacts to kdeaddressbook

I have about 1800 contacts with General fields, Detail fields, and ALL Fields sections. 1800 are in General fields, most are also in Detail fields, and a good number in All Fields plus my notes connected to each contact. This is a lot of comma separated material to move to KDEaddressbook and utilize the other offerings of Kontact. Before i go download this, i would like to inquire your thoughts on my making the move before i try from outlook 365 to KDEKontact.
Thank you…b3
