I have a spreadsheet with about 30,000 records in it, that has names &
addresses, as well as ID numbers in it.

The problem is, there are some duplicates in it.

Not strictly duplicates, but duplicates nonetheless.

The id numbers are unique, but other columns may only be similar.

They'd have the same City, State & Zip, but there may be differences like:

Bud's Country Store
123 N Main St
Podunk, IA 40444

Buds Country Store
123 North Main Street
Podunk, IA 40444

Even though the ID number would be unique for each of them, these are
duplicate records, even though there are slight differences in the way
the name is listed or even in the address line.

Is there a macro that I can use to highlight & remove duplicates in a
case like this?

Thanks,

BC
