How do I fix Shopify CSV encoding errors?

Upload your Shopify product CSV to CSVFixer. It auto-detects encoding issues like Invalid UTF-8 or Latin-1 and converts to clean UTF-8 for Shopify import.

Why does Shopify say my CSV has invalid UTF-8 encoding?

This happens when your CSV was saved from Excel or a non-UTF-8 source. CSVFixer detects and fixes the encoding automatically.

Why Shopify CSV imports fail

Wrong encoding

Shopify requires UTF-8. Excel exports can use Latin-1 or include a byte-order mark, producing an “Invalid UTF-8 encoding” error.

Delimiter mismatch

Supplier files often use semicolons or tabs. Shopify expects comma-separated values and may otherwise read everything into one column.

Header problems

Missing or renamed fields such as Handle, Title, Vendor and Option Name can stop an otherwise valid import.

Error message	Likely cause	Repair
Invalid UTF-8 encoding	Latin-1 or BOM	Re-encode as clean UTF-8
Title can't be blank	Broken quoting or columns	Normalize delimiters and quotes
Unknown column	Renamed or extra header	Match Shopify headers
Garbled product text	Encoding mismatch	Repair before import
