Fix Shopify CSV invalid barcode errors
Barcode fields can break product imports when values are malformed, mixed-format, or duplicated across incompatible variants.
Why Shopify throws this error
Barcode values are expected to be clean identifiers. Non-printable characters, formatting noise, or invalid lengths can fail parsing.
Common causes
- - Barcode includes spaces, symbols, or hidden spreadsheet characters.
- - Mixed barcode standards in one column without normalization.
- - Duplicate barcodes unintentionally assigned to unrelated variants.
- - Barcode stored as scientific notation after spreadsheet edits.

Manual fix steps
- 1. Format barcode column as plain text before editing.
- 2. Strip spaces and symbols so values are clean alphanumeric strings.
- 3. Standardize barcode length based on your catalog policy.
- 4. Confirm duplicates are intentional only for the same physical item.
RowReady-assisted fix path
- 1. Run a file check to detect malformed or duplicate barcode patterns.
- 2. Use row-by-row output to correct affected variants.
- 3. Export and validate again before Shopify import.
