Schema Markup Checker
Scan any URL for JSON-LD structured data and validate its syntax.
Structured Data Validator
Extract, validate, and preview JSON-LD schema markup from any webpage to ensure Google Rich Snippets compatibility.
Ready to Extract
Enter a URL above to scan the page and extract all embedded Schema.org JSON-LD markup.
How does it work?
This tool fetches the HTML of the provided URL and searches for <script type="application/ld+json"> tags. It extracts the raw JSON payload and attempts to parse it to ensure it is valid, well-formed JSON.
Why is this important?
If you have a trailing comma, missing quote, or other syntax error in your JSON-LD, search engines like Google will silently ignore the entire block of structured data. This means you won't get any rich snippets or enhanced search results. Validating your JSON syntax is the critical first step in implementing Schema markup.
Note: This tool only checks for JSON syntax errors. To fully validate against Google's rich result requirements, use the Google Rich Results Test.
