CSV duplicate remover
The current validator deduplicates only destinations that declare a unique identifier—Email, SKU, or id—and always keeps the first occurrence within the 100-row run. Shopify product Handles are excluded because repeated Handles can represent variants or additional images. Arbitrary columns and alternate survivor strategies are not yet implemented.
Before: 100 preview rows · duplicate destination identifiers
After: Later duplicate rows excluded · first record kept
What is available now
- Uses a destination field explicitly declared as unique
- Matches duplicate identifiers case-insensitively
- Keeps the first row and reports each later duplicate
- Never deduplicates grouped Shopify product Handles
