Duplicate rows
What they are and how to fix them
What are duplicate rows?
Duplicate rows are identical copies of another row. They inflate counts, break unique constraints, and distort reports. RxLint finds all duplicate groups and lets you remove extras with one click so your data is deduplicated.

Frequently asked questions
Are duplicate rows always bad?
For unique keys such as emails or IDs, duplicates are usually mistakes. For logs or event streams, repeated rows might be valid. RxLint surfaces them so you can decide what to keep.
Can I remove duplicates automatically?
Yes. RxLint groups duplicate rows and offers a quick fix to remove the extras while keeping one row per group.
