DataLayer Inspector - Validate & Improve Your GA4 Ecommerce Tracking

Explore GA4 Ecommerce Schema Examples

Use this tool to explore example dataLayer.push() formats for common GA4 ecommerce events like view_item, add_to_cart, and purchase. You can select a schema from the dropdown to preview its recommended structure and field comments.

Extract Ecommerce Events from Your Site

To extract ecommerce tracking data directly from your site, open your browser's developer console (usually by pressing F12 or Right Click → Inspect → Console) and paste the following code snippet. This will return any ecommerce-related dataLayer.push() entries from the current page, which you can then copy and paste into the validator below.

If you are having troube, try typing 'allow pasting' into the console first.

dataLayer.forEach((entry, i) => {
  let ecommerceEntry = null;

  // Case 1: Plain object with ecommerce
  if (entry && typeof entry === 'object' && entry.ecommerce) {
    ecommerceEntry = entry;
  }

  // Case 2: Arguments-like object with ecommerce inside the 3rd param
  else if (
    Object.prototype.toString.call(entry) === '[object Arguments]' &&
    typeof entry[2] === 'object' &&
    entry[2] !== null &&
    entry[2].items // or entry[2].ecommerce if it's standard ecommerce structure
  ) {
    ecommerceEntry = {
      event: entry[1] || 'unknown_event',
      ecommerce: {
        ...entry[2]
      }
    };
  }

  if (ecommerceEntry) {
    const formatted = JSON.stringify(ecommerceEntry, null, 2);
    console.log(`// Ecommerce Push ${i + 1}\ndataLayer.push(${formatted});\n`);
  }
});
