CSV Duplicate Remover

Remove duplicate rows from a CSV file. Choose which columns define uniqueness.

About CSV Duplicate Remover

Clean your dataset by removing duplicate rows. You can deduplicate based on all columns (exact row match) or select specific key columns. Choose whether to keep the first or last occurrence of each duplicate group. Case-insensitive matching normalises capitalisation before comparison.
