CSV and data tool

Remove duplicate CSV rows

Upload a CSV file, detect duplicate rows, remove repeated entries, and export a deduplicated CSV file.

What this tool is for

Exact row deduplication removes repeated records, but it does not necessarily detect duplicate real-world entities. Two invoices can share a customer name and amount while still being legitimate separate transactions.

How to use it

  1. Review whether the CSV contains a header row and which fields define an exact duplicate.
  2. Run duplicate removal and note how many rows remain.
  3. Inspect repeated-looking records and save a new export rather than overwriting source data.

Example workflow

If the same exported line appears twice byte-for-byte, exact-row cleanup is appropriate. Two different orders for the same customer should usually stay separate.

Important limitations

  • Case, spacing and punctuation differences can prevent exact duplicate detection.
  • Do not deduplicate financial or administrative records without checking the intended uniqueness rule.
