Spec Hero stores every specification as a real Shopify metafield, so it works with Shopify's own storefront filters, search, and bulk editor. Define a global spec set plus a set for each product type, then fill in values across your catalog with a spreadsheet-style grid or a CSV import. Spec tables render in your product page HTML, including a full variant matrix. A guided setup walks you through creating fields and turning on filters, then checks your store to confirm each step is live.

• Specs stored in your own Shopify metafields, so native filters work
• A global spec set plus sets per product type, assigned by collection or tag
• Fill hundreds of products from a grid, a paste, or a CSV with error reporting
• Variant matrix tables that put every size or length in one spec sheet
• Side-by-side compare that hides identical rows and shares as a link
