I appreciate all the helpful information, but I hate to say I am an Excel
novice and unfamiliar with simple things such as "helper column" and "macro".
What I need is a very simple step by step direction in how to complete this
task. Sorry I am such a klutz, but thanks ahead of time for your help.

I have an existing worksheet with over 50,000 rows and 15 columns. Several
columns have information in all uppercase. I need to convert these words
into proper case. The information given in Excel Help only gives information
about changing individual cells. Does anyone have any suggestions?
