Find repeated SKUs in a pasted list
Copy only your SKU column and paste one identifier per line. Remove the header first. This small checker finds repeated values; it does not parse a full CSV or connect to your store.
Blank lines are skipped. Leading zeros and literal * or ? characters are preserved. Line references refer to your pasted list, not the original spreadsheet.
Ready. Paste a list or try the sample.
Processing: This checker processes the pasted list in this page and does not submit it to Altrix Web. It does not save the list in browser storage. Clearing the form removes its current contents and results. The website’s usual privacy policy still applies to visiting this page.
How to review the results
Check the matching options before interpreting repeats. For example, shirt-01 and SHIRT-01 are different unless you choose to ignore case. Trimming removes spaces at the start and end, but leaves spaces inside an identifier. Review whether repeats represent a genuine catalogue mistake before changing any records.
The tool displays up to 200 repeated groups and 20 line references per group. Summary counts cover the full accepted list. A repeated SKU is a review signal, not proof that an import will fail. Spreadsheet formatting changes, such as previously removed leading zeros, cannot be repaired here.
