Structured Data Tester
Paste JSON-LD or a URL's HTML to see which schemas got detected, the key fields, and any parsing errors. Runs locally—no data is stored.
Test your structured data
How it works
- Parses JSON-LD blocks from your input (or pulls them out from pasted HTML).
- Lists detected
@typevalues and flags if required fields are missing for common types (Article, Product, FAQ). - Shows raw parsed JSON for you to copy/debug. Runs fully in-browser.
