Shopify CSV handle repair
Shopify CSV Duplicate Handle Error
Shopify uses the Handle column as the product URL slug and product identity in imports. EcomCSVFix finds duplicate handles and safely renames duplicate products so the import can continue.
What causes this error
- Rows were copied and pasted, leaving two different products with the same Handle value.
- Two products have the same Title, and a handle generator created the same slug for both.
- Variant rows are sharing a parent handle incorrectly, making separate products look like one product.
- A supplier export reused generic handles such as product, item, or blue-t-shirt across multiple SKUs.
How to fix it
Option A: fix it manually
- Open the file and sort by the "Handle" column so duplicates sit next to each other.
- Check whether repeated handles are true variants of one product or separate products.
- For separate products, rename duplicates with clear suffixes such as -2, -3, or a product-specific word.
- Keep real variant rows under the same Handle, with blank Title on subsequent variant rows when appropriate.
Option B: fix it automatically
- Upload the CSV and EcomCSVFix groups repeated handles to detect true duplicates.
- Download a fixed file where duplicate products receive unique handles automatically.

FAQ
What is a Shopify handle?
A handle is the URL-friendly product identifier Shopify uses in product URLs and imports, such as blue-t-shirt.
Are duplicate handles always wrong?
No. Variant rows for the same product should share the same Handle. The problem is when separate products accidentally share one handle.
Can I use spaces in handles?
Use lowercase letters, numbers, and hyphens. Handles with spaces or special characters should be converted to clean slugs.
Will changing a handle affect product URLs?
For new imports, handles become product URLs. For existing products, changing handles can affect URLs, so review duplicates before updating live products.
