About This Launch
Catalog Preflight is a free browser-local checker for Shopify product CSV files. It highlights structural conditions to review before a bulk import, including incomplete product rows and image alt text. CSVs stay in the browser; the tool does not connect to a Shopify store or change catalog data.
Why I Built This
Bulk Shopify CSV edits can be difficult to review before an import. Catalog Preflight was built as a focused preflight step so a merchant can inspect a working copy locally before sending it to a live catalog.
