JSON-LD Schema Validator
Find and fix every structured-data error on your page - free, with exact fixes.
Why validate JSON-LD?
Google, Bing, and AI search engines (ChatGPT, Perplexity, Gemini) rely on schema.org JSON-LD to understand pages and decide whether to show rich results, citations, or knowledge-panel data. A single JSON parse error, a missing required field on an Article or Product, or a mistyped @typesilently disqualifies your page from rich results - and there is no warning in Search Console.
What this tool checks
We fetch your page, extract every <script type="application/ld+json"> block, and run it through a schema.org validator: JSON syntax, required @context and @type, required fields per type (Article, Product, FAQPage, LocalBusiness, BreadcrumbList, HowTo, Recipe, Event, VideoObject, Review, JobPosting), common mistakes like lowercase types, relative image URLs, non-ISO dates, and prices that contain currency symbols. Every error comes with a copy-paste fix.
