How it works
The first row is treated as the header and always kept. Every following row is compared either across all columns or by one chosen key column, case-sensitively or not, and duplicates are dropped keeping either the first or last occurrence.
Frequently asked questions
How is this different from the CSV Cleaner?
The cleaner normalizes formatting (whitespace, blank rows/columns); this tool specifically compares row content to find and remove true duplicates.
