I had encountered this problem while carrying out mail merge. Usually names are stored in a single field. In order to carry out mail merge for a letter/mailer, last names needs to be stored in a separate field to faciliate merge as Dear Mr/Ms last_name
The original list is stored in column A whereas the desired lists in columns B and C.
Formula used in cell B2 is =RIGHT(A2,LEN(A2)-FIND(” “,A2))
Formula used in cell C2 is =LEFT(A2,FIND(” “,A2)-1)
Dragging these formulas give us the desired results in columns B and C
Alternative solution
1. Select A2:A8
2. From toolbar –>Data –> Text to Columns… –>Delimited–>Space–> Finish
Make sure that column B has no data to begin with. If there is some data already, insert a blank column B.
Appears as First Name, Last Name in columns A and B
