Fix Shopify CSV duplicate handle overwrite issues
Multiple products sharing one Handle can cause accidental merges or overwrites during import.
Why Shopify throws this error
Handle is the product grouping key. Duplicate handles across unrelated products can collapse rows into one product context.
Common causes
- - Copied rows reused an old Handle value.
- - Bulk slug generation produced collisions.
- - Parent product and unrelated child rows share a handle by mistake.
- - Legacy exports were merged without handle deconfliction.
Corrected CSV example
Handle,Title,Variant SKU classic-tee,Classic Tee,TEE-BLK-S logo-mug,Logo Mug,MUG-WHT-12
Manual fix steps
- 1. Group rows by Handle and review whether each group is one real product.
- 2. Assign unique handles to unrelated products.
- 3. Keep intentional variants under a single shared handle.
- 4. Re-check for downstream SKU and option conflicts.
RowReady-assisted fix path
- 1. Upload the file and open duplicate-group warnings.
- 2. Use guidance to split collisions into correct handles.
- 3. Download clean output only after collision count is zero.
