Shopify CSV illegal quoting: what the error means
Illegal quoting usually means a comma or double quote inside a product field was not escaped as CSV requires. Product descriptions and tags are common places for this to happen.
Safe next steps
- Keep a copy of the original export.
- Check that the file is a product catalog CSV, not orders or customers.
- Run a free preflight to identify quoting and row-structure issues.
The $29 rescue package can normalize deterministic CSV quoting and return a change report. It does not invent prices, SKUs, inventory, options, images, or product claims.
