How to Scrape Custom Metafields Visible on the Shopify Frontend

Shopify store owners use custom metafields to display technical specifications, fabric descriptions, safety details, or sizing tables on their product pages. These fields contain key information that is not stored in standard columns. Learning how to scrape Shopify metafields helps you extract these details for your own catalog audits.

How Metafields are Rendered on the Frontend

Metafields are often loaded as plain HTML elements or JSON structures in the page source. To extract these custom fields:

• Inspect the DOM: Look for data attributes (such as `data-metafield-spec`) containing the technical values.
• Query JSON Endpoints: Check if the metafield details are exposed in the product's backend data endpoints.

Extracting Technical Specifications Natively

Use local browser scraping tools to parse these custom frontend attributes, saving the technical values to structured spreadsheet columns for your product research.
