JSON-LD Validator
Paste a JSON-LD block to check it's valid JSON, has the required @context and @type, and includes the fields commonly expected for its type.
Issues
No issues found.
Validation happens entirely in your browser — nothing you paste here is uploaded anywhere.
Processing happens locally in your browser. Nothing you enter is uploaded.
How It Works
Paste the contents of a <script type="application/ld+json"> tag to see validation results.
Example
An Article block missing a "headline" field is flagged as a warning, since that field is commonly expected for that type.
Frequently Asked Questions
- Does this check if Google will show rich results for my page?
- No — it checks the JSON-LD's own structure and common fields. Whether a rich result is actually shown also depends on Google's own policies and page content, which this tool can't predict.
- Is my data uploaded anywhere?
- No — validation happens entirely in your browser.
