Structured data validator for Schema.org JSON-LD.

Validate JSON-LD syntax before deployment

Paste raw JSON-LD or a complete application/ld+json script block. The validator parses the markup locally, reports syntax failures, and provides line and column details when the browser exposes an error position.

Check types and common implementation fields

The preflight checks @context, @type, and practical fields for Product, FAQPage, Article, Organization, LocalBusiness, BreadcrumbList, HowTo, Event, JobPosting, VideoObject, and other common Schema.org types.

Inspect nested FAQ and breadcrumb entities

FAQ entries are checked for Question, visible name text, and accepted Answer text. Breadcrumb items are checked for position, name, and item so nested mistakes are easier to find before launch.

Confirm eligibility with official validators

Passing local checks does not guarantee a Google rich result. After fixing errors, test the final public URL with Google Rich Results Test or validate the markup with Schema.org tools, then monitor enhancement reports in Search Console.

What does this structured data validator check?

It checks JSON syntax, @context, @type, common required and recommended fields, FAQ Question and Answer objects, and BreadcrumbList item fields.

Does a valid result guarantee Google rich results?

No. Google no longer shows FAQ rich results, and other search features depend on supported types, visible page content, quality guidelines, indexing, and Google's systems. Use official testing tools on the final public page.

Can I paste a full JSON-LD script tag?

Yes. The validator accepts raw JSON or one or more application/ld+json script blocks and formats successfully parsed markup for copying.
