Validate JSON-LD structured data syntax and check for required fields per schema.org type.
100% in-browser — validates JSON syntax and checks for commonly required fields per schema.org type (Article, Product, FAQPage, Recipe, etc.). It doesn't call Google's live Rich Results Test — use that alongside this for final validation before launch.
Schema Markup Tester validates that pasted JSON-LD is syntactically correct, confirms the @context is schema.org, detects the @type, and checks for commonly required fields for that type (Article, Product, FAQPage, Recipe, and more).
Paste your JSON-LD structured data
From a page's <script type="application/ld+json">.
