You can use a formula like this in an additional column (starting in C2, for
example):
=IF(A2<"",A2,IF(B2<"",C1,""))
If column A has a value, it will be return that; if there is value, and the
column B is not empty, it will return the value just over it on its own
column, that it will be the repeated value expected. If both columns are
blank, it will return blank.
You can later copy/paste values from this column to the original one.

Hope this helps,
Miguel.

I have an Excel worksheet with a few thousand rows. The first 2 columns look
as seen below. I need the Account # of every customer to be on every row.
As of now, the Account # is only on the First row and the rest of rows blank.
What type of formula can I create to replace the blank rows after the
account # with the account # that corresponds to customer. See below for
complete description.
