Find duplicate SKU values in a product export
Repeated stock keeping units can make product listings, inventory counts, and marketplace uploads harder to manage. Upload a CSV product list, select the column containing SKUs, and review the repeated values before downloading a report.
How to find duplicate SKUs
- Select a UTF-8 CSV product file. The tool will try to recognize a column named SKU.
- Choose the correct SKU column and decide whether to ignore case and surrounding spaces.
- Review the duplicate values, then download matching product rows or a summary of SKU counts.
Frequently asked questions
Does the finder change my original file?
No. It reads the file in your browser and offers a separate download with matching rows or a summary.
Are blank SKU cells reported as duplicates?
No. Blank values are skipped so empty cells do not appear as repeated product codes.
Can I choose a column with a different name?
Yes. Select any column from the CSV header row, even if it is not labeled SKU.
