CATALOG PREFLIGHT

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.

See a real baseline comparison

In this short browser walkthrough, a fresh current export contains a variant option combination that is absent from the planned CSV. The checker flags it locally before import.

Select a UTF-8 Shopify product CSV to begin.

What this checks

Required Handle and Title headers
Blank handles and duplicate handle groups
Image rows without a public Image Src URL
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 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.
