A local structural validator for five types. No remote crawl, complete vocabulary validation or guarantee of rich results.
How to use
- Choose a schema type and enter facts that are visible on your page. Use Question | Answer or Name | URL pairs for FAQs and breadcrumbs.
- Generate JSON-LD, or switch to Validate pasted JSON-LD to check a supported object, array or @graph. Review errors and warnings.
- Copy or download the JSON, place it inside a script with type application/ld+json, and check the final published page with the relevant search-engine tools.

Frequently asked questions
Is this free, and do I need an account?
It is free, no sign-up. Tool processing happens locally in your browser. Inputs and outputs are not uploaded to a processing API. Usage events contain only the tool name and action.
Is this a complete Schema.org validator?
No. It parses JSON and checks a declared subset: context, supported types, names, URL formats, offer values, FAQ answer structure and breadcrumb positions. It does not resolve custom contexts, validate every vocabulary property or test the published page.
Will valid markup guarantee a Google rich result?
No. Search appearance depends on eligibility, content, policies and search-engine decisions. Software rich results require actual rating or review evidence. This tool never invents reviews, ratings, availability or product claims.
Does Google still display FAQ rich results?
Google retired FAQ rich results on May 7, 2026 (Google Search Central, verified October 9, 2026). FAQPage remains a Schema.org type and can describe visible questions and answers for other consumers. Generating it does not promise an expanded search result. Google Search Central: May 2026 updates ↗
Can I validate JSON-LD without fetching my website?
Yes. Paste JSON-LD itself rather than an HTML script wrapper. Validation runs locally and does not fetch URLs. Supported @graph nodes inherit the root Schema.org context.
How do I keep the generated claims honest?
Use your real name, canonical URL, product price and visible content. Keep the markup aligned with license and product terms. Add review or rating data only when you have genuine, eligible evidence.
