Check pasted JSON-LD for JSON syntax and selected context, type and property-presence hints. This is a limited local check, not full validation. The scope note below explains what needs separate review.
Schema Testing Tool is a free Schema & Structured Data Tools utility that runs entirely in your browser — nothing you enter is uploaded.
How to use Schema Testing Tool
- Paste the documented input format into the input field.
- Read the limited checks and any reported missing fields.
- Use a full implementation or the relevant consumer’s test for complete validation.
About this tool
Parses pasted JSON, or the first matching JSON-LD script block, and reports basic @context, @type and selected top-level property-presence hints. It follows arrays and @graph for those hints. It does not expand JSON-LD contexts, verify vocabulary terms or property values, inspect a live URL, or establish Google rich-result eligibility.
Review the generated values before publication. JSON serialization alone does not establish vocabulary correctness or search-feature eligibility.
