GOOD TO KNOW

How do I remove duplicate rows from CSV?

01

Exact means exact

Every cell in a row must match. Similar names, different capitalization, or extra spaces are not treated as duplicates.

02

The first row is the header

The heading row is never compared with the data. Of repeated data rows, the first occurrence is kept.

03

No fuzzy matching

This first version avoids guessing whether two customers or products are the same. That protects meaningful differences.
