Shopify Product CSV Bulk Import

I have several CSV files that hold my entire product catalogue and I need them turned into live Shopify listings without a hitch. Each row already carries the essentials—product titles, detailed descriptions, prices, inventory counts, images, and tags—and I want every one of those fields to land in the right spot on the storefront. Beyond the basics, the spreadsheets include a few custom attributes such as material grade, supplier SKU, and other metafields that my theme relies on. These unique columns must be mapped properly so they remain visible and editable inside the Shopify admin. To be clear, the job is not data entry by hand; it’s about preparing the CSVs, configuring the import (or the preferred bulk-upload tool), and validating that everything displays exactly as intended. If a small test batch helps catch errors early, I’m all for it. Deliverables I’m expecting: • Cleaned and formatted CSVs ready for Shopify • Successful import of all products, images, and tags • Custom fields/metafields created and linked correctly • Post-import report summarising any fixes applied and a template I can reuse If you’ve wrestled with Shopify’s import quirks before and know how to preserve custom attributes, I’d love to get this done quickly and cleanly.
