Your catalogue has drifted: inconsistent titles, missing specs, duplicated SKUs, and a product feed that will not import cleanly. I bring it back to one standard.I work on Shopify and WooCommerce stores daily as part of a large multi-site e-commerce delivery program, so catalogue cleanup is routine work, not a guess. One cleanup pass plus one feed or sync per job, delivered as a clean export you can import directly.Step by step:You export the catalogue and tell me the rules you want (title format, units, required fields, how duplicates should merge).I clean it, apply the rules, and flag the rows that need your decision.You get the clean export plus a short change log.One catalogue and one sync or feed format per job. Bulk rewriting every product page, redesigning templates, or a custom storefront is quoted separately.
