Structured Data Validator
Validate schema.org JSON-LD for rich results.
This free structured data validator checks schema.org JSON-LD markup for Google rich results. Paste raw JSON-LD or an entire HTML page — the tool extracts every <script type="application/ld+json"> block, confirms the JSON parses, verifies each item declares an@context and @type, and checks the required and recommended properties for common types (Product, Article, Recipe, Organization, LocalBusiness, Event, FAQPage, BreadcrumbList and more).
Unlike a plain linter it validates nested items too — anoffers, author or address object is checked against its own type — and it validates property values: dates and date-times must be ISO 8601, durations must be ISO 8601 (PT30M), URLs must be absolute, prices and ratings must be numeric, and enum fields (availability, condition, event status) must be real schema.org values. Each eligible item is labelled with theGoogle rich result it qualifies for.
