I have two excel workbooks that I need to update data from workbook 1 into workbook 2. The workbooks are both customer lists with customer assigned to each person. In one book I have a customer code (A,B, or C) assigned to each customer number. I need to copy that code for each customer and enter it in a new column in workbook 2.
For example cust# 123 has code B assigned to them, I need to go into workbook 2 and assign B to cust# 123. I have about 11,000 entries to do this for. Any help?
