What is the JSON-LD Validator?
Validate JSON-LD structured data syntax, check for errors, and preview parsed schema output.
The JSON-LD Validator checks your structured data markup for syntax errors, missing required properties, and formatting issues. Paste your JSON-LD code to get instant validation with clear error messages pointing to the exact issue. Valid structured data is essential for earning rich results in Google - star ratings, FAQ dropdowns, recipe cards, and more. Catch and fix errors before deploying to prevent failed rich result eligibility.
