Frequently asked questions
What columns does a Shopify product CSV require?
Shopify requires a Handle for every row and a Title for every product. Recommended columns include Body (HTML), Vendor, Variant SKU, Variant Price, Variant Inventory Qty, option name/value pairs, Image Src, and Status. CatalogWash maps your supplier headers to these fields and fills safe defaults like Status, fulfillment service, and inventory policy on export.
How do I map supplier column names to Shopify fields?
CatalogWash auto-maps common supplier headers (for example, "Item Name" to Title or "SKU Code" to Variant SKU), lets you adjust every mapping manually, and can suggest mappings with AI using only your headers and a small sample that is sent after you ask for it.
Can I convert an Excel (XLSX) file to a Shopify CSV?
Yes. CatalogWash parses CSV, XLSX, and XLS files directly in your browser, then exports a clean Shopify-ready CSV regardless of the original format.
Is the conversion free?
The import health report and product preview are free. The fixed Shopify-ready CSV export costs $9 per cleanup session — re-export the same file as many times as needed for 24 hours.
