Check the CSV before Shopify does.
Choose a Shopify product CSV and get a local preflight report for common structural problems: blank handles, image rows that do not use a public URL, variants missing option values, repeated handles that should be reviewed, and missing image alt text. Nothing is uploaded; the parser runs in this browser.
Local CSV check
Select a UTF-8 Shopify product CSV to begin.
What this checks
- Required
HandleandTitleheaders - Blank handles and duplicate handle groups
- Image rows without a public
Image SrcURL - Variant rows missing
Option1 Value, sharing a repeated option-value combination, or inconsistently filling key variant fields - Optional baseline comparison that flags current variant option combinations absent from the planned import
- Blank cells that can behave differently from omitted columns during update imports
- Image-alt-text coverage, plus a local review CSV with title/color-based draft text
This is a structural aid, not an import simulator. It does not log into Shopify, fetch image URLs, change a store, or prove that an import will succeed. Check Shopify’s current CSV documentation before an actual import.
Need a safe way to test your review process?
Get the free Shopify CSV Variant Test Pack: three synthetic CSVs that exercise duplicate option combinations, repeated product-start rows, and included blank fields in an update file. It is a test resource, not an importer.

This short demonstration shows the exact patterns included in the free test pack before you open it.
Need a repeatable review process?
The $9 implementation kit adds the current unlimited offline checker, annotated examples for product-image and variant rows, an import-review worksheet, and a concise field-by-field guide.

Want a manual review before you import?
The $29 Review + kit option includes a plain-language structural review of one non-sensitive proposed product CSV within one business day, plus the implementation kit. It covers headers, handles, image URLs, variants, and overwrite-risk fields. It does not log in to Shopify, modify a store, recover data, or guarantee import success.
