Schema Validator Lite
Paste JSON-LD to check it is valid JSON, declares @context and @type, and to flag missing fields common schema types expect.
Catch structured-data mistakes fast
Most broken structured data fails for boring reasons — a trailing comma that makes the JSON invalid, a missing
@type, or an omitted required field. This lightweight validator catches those quickly: it parses your
JSON-LD, confirms it declares a context and type, identifies the schema type, and warns about fields that common
types like Article, Product, LocalBusiness, and FAQPage are expected to include.
Think of it as a fast first pass while you're writing markup, not a replacement for the official tools. Once it's clean here, run the same code through Google's Rich Results Test and the Schema.org validator to confirm rich-result eligibility. Paste your JSON-LD above to see the checks run live.
Private and instant
Validation runs entirely in your browser — nothing is uploaded.
Frequently Asked Questions
What does this validator check?
It confirms your JSON-LD is valid JSON, that it declares @context and @type, and it flags missing fields that common schema types (Article, Product, LocalBusiness, FAQPage, and others) usually need.
Is this a full schema.org validator?
No — it is a fast, lightweight structural check for the most common mistakes. For official validation, also run your markup through Google’s Rich Results Test and the Schema.org validator.
Why do I get an “invalid JSON” error?
Usually a trailing comma, a missing quote, or an unescaped character. The validator points to the JSON parse error so you can fix the syntax before checking structure.
Is this tool free and private?
Yes. Validation runs entirely in your browser — nothing is uploaded or stored.
