Frequently asked questions
Common questions about checking migration CSV files.
Is this a WooCommerce to Shopify converter?
Not yet. This page is a preflight checker that finds CSV quality problems before conversion or Shopify import.
Can I upload supplier CSV files?
Yes. The checker works best when the file contains Shopify-like columns or columns that can be matched to SKU, barcode, vendor, price, handle, and options.
Why check before migration?
Bad SKUs, prices, handles, and variants create rework during migration. A preflight report helps clean the file before mapping or importing.
Can it produce a clean Shopify CSV?
It can auto-fix safe formatting issues and export a clean CSV, but field mapping from WooCommerce to Shopify is a later feature.
