Schema Validator is a free Schema & Structured Data Tools utility that runs entirely in your browser — nothing you enter is uploaded.
How to use Schema Validator
- 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.
Schema Validator runs entirely in your browser. Schema Validator assembles valid JSON-LD locally so you can paste it into your page.
Everything is generated on your device with nothing uploaded. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
