How to fix it
- Open the file in a plain text editor at the line the checker names and look for an unmatched ".
- Inside a quoted cell, a quote must be written twice ("").
- Save the file as "CSV UTF-8".
Example
A file with this problem
Title,URL handle,Price "Cotton Tee,cotton-tee,20.00
What the checker says about it
- A quoted field that starts on or after line 2 is never closed. The file may be cut off or have a stray double quote. Shopify reports this as "Illegal quoting" or "Missing or stray quote".
Once the listed rows are fixed, check the file again; the checker also looks for every other problem Shopify documents, so you do not trade one error for the next.
