Fix Shopify CSV “options are not unique” errors
Find duplicate option combinations within the same product handle before importing a Shopify product CSV.
Shopify reports “options are not unique” when two variants of the same product use the same option values. Compare all three option columns within each handle. A repeated handle on an image-only row is normal.
- Group rows by Handle or URL handle.
- Compare Option1 value, Option2 value and Option3 value together.
- Review repeated combinations. Remove an accidental duplicate, or correct the option values from your source catalog.
- Check the result, then review Shopify’s import preview.
The checker identifies duplicate combinations and gives the physical line number, including files with quoted multiline descriptions.
