I can start with just a few rows, but will add to it each day, about 100 each
day. Column B will have the house address, and I need to know if duplicates
are being added each day, and which ones they are. Column C will be either
the same address or a different address, depending on how the mail was set
up. I will need to search column C for duplicates also. After 5 days I will
start a new spreadsheet. Will this work?
