About this tool

Schema JSON-LD Validator parses pasted structured data and checks for a Schema.org context and top-level @type values, including @graph nodes. It is a focused preflight check rather than a replacement for Google’s rich-result tools.

How to use

  1. 1Paste one JSON-LD object.
  2. 2Resolve JSON parsing errors.
  3. 3Confirm context and types.

Benefits

  • Focused, understandable checks.
  • No remote website fetching.
  • Runs locally in your browser.

Validate syntax first, then verify search-feature eligibility

Practical example

A JSON-LD block can be valid JSON yet use a misspelled Schema.org property. Conversely, valid vocabulary does not guarantee that Google supports a rich result for that type.

Interpreting the result

Resolve JSON errors, confirm every type and property against Schema.org, then test the deployed page with the search engine’s official rich-result tool and monitor Search Console.

Limits and common mistakes

This local check cannot promise indexing, ranking or a rich result. Search engines apply feature-specific required fields, content policies and quality systems beyond structured data.

Frequently asked questions
