What this checker covers
Current and legacy Shopify headers, quoting, product groups, option combinations, prices, booleans and duplicate SKUs. Custom fields are preserved. Image availability, taxonomy, inventory locations, GTIN ownership and your store’s existing data are not verified.
Uneven rows, duplicate columns and damaged quoting may need correction in the source file. This tool never deletes or merges product rows.
Shopify CSV requirementsHow it works
- Choose a Shopify product CSV or load the sample.
- Inspect errors by row; choose your number format before changing ambiguous prices.
- Review the proposed changes and export a corrected copy. Keep the original and test a small import first.
Example & practical use
Check a supplier export for missing product titles, inconsistent prices and repeated product variants without losing leading zeros in identifiers.
