The row-by-row diagnostic is free and runs in your browser. If RowReady finds safe repairs you want to export, the repaired file is a one-time $9 USD—no signup or subscription.
Check my CSV free →Shopify reads the first CSV record as column names. A header can look right in a spreadsheet but still fail because of different capitalization, leading or trailing spaces, or a name from an older export format. Compare the entire header row with a fresh Shopify product export instead of correcting only the column named in the message.
Do not rename unfamiliar columns by guesswork. RowReady detects supported current and legacy product headers, proposes exact formatting corrections where the mapping is unambiguous, and leaves business data unchanged. If a required field is truly absent, add it deliberately in your spreadsheet.
