De-duping a mailing list

Hi everyone,

I have a spreadsheet consisting of about 150 rows. It contains the full names of the people in Column F and each of the rows have either a “billing address”, “home address”, “work address” or “PO address”. The spreadsheet is sorted by column F (Full name) in alphabetical order so that you can clearly see the duplicate names. In fact, the duplicates in column F were identified in another workbook and copied into the current separate one so that duplicate customer records could be removed in preparation for a mailout.

In most instances there are only two duplicates for any particular customer but in some cases there could be 3, 4 or even 5. The goal of the exercise is to keep the customer row that has a home address as that is the preferable address to send to. If there’s no home address, then keep the billing address. If no billing address, then keep the work address. If no work address keep the PO box address.

My first attempt at this de-duping was to sort by home address, then by billing address, then by work address, then by PO box address. Even though this helped identify which entries had a home address, it still hasn’t solved the problem as it hasn’t de-duped as I would like and as I described in the previous paragraph.

Can anyone tell me if this can be done in excel and if yes, how I would go about it? Or would I would need to get some vba code written?

Would really appreciate any advice.

    on the menu ribbon select the data tab, then select filter.

    then on the home address column only show non blank cells.

    then copy the records to another sheet.

    then set the filter to show all, then move to filtering the next criteria and copy the filtered data into another sheet and so on until you have copied all records that contain complete records for each home address, billing address, work address, and PO Box address.

    now you have four lookup tables for each criteria.

    next normalize all the names where you only have one instance for each name and put those name in its own sheet, this sheet is where you will be putting your formula to lookup the name in the home address lookup table first if it exists, then so on and so forth until all records are normalized.

    yes it is labor intensive, but once you have normalized this data, it can then be stored in a relational database (if this is a long term endeavor) where if you would ever need to do this exercise again all you would have to do is to create a query :)

    if you had thousands of rows of data writing vba code would be better, but for 150 rows of data manually doing it is less of a headache even for someone who is an expert writing vba code.
