Schema JSON-LD Validator

Paste JSON-LD or fetch from any URL. Validates against Google's required fields, checks dates, URLs, and nested objects.

How this validator works

This tool parses JSON-LD and checks it against Google's documentation. It verifies required fields for 15 schema types, validates ISO 8601 dates, checks URL formats, and inspects nested objects like author and publisher. For live page validation, use Fetch & Validate to pull all JSON-LD schemas directly from any URL.

For even deeper analysis — cross-referencing schema data with actual page content — use the Lumina Extension.

FAQ

What schema types are supported?+
Article, NewsArticle, BlogPosting, Product, FAQPage, LocalBusiness, Organization, Person, BreadcrumbList, Event, Recipe, HowTo, VideoObject, WebSite, and Review — each with type-specific required and recommended fields.
How is this different from Google's Rich Results Test?+
Google's tool checks rich result eligibility. Ours focuses on field-level validation — required fields, date formats, URL validity, nested objects. Both complement each other.
Can I validate from a live URL?+
Yes! Enter any URL in the "Fetch & Validate" bar. The tool fetches the page, extracts all JSON-LD blocks, and validates each one.

Deep schema validation on every page

Lumina cross-checks schema data against actual page content — prices, dates, FAQs, addresses.
