Schema Markup Validator
Paste your JSON-LD structured data (with or without the surrounding script tag) and get instant feedback on syntax, required properties and common rich-result mistakes.
Script tags are stripped automatically. Nothing leaves your browser.
Paste your markup to validate it.
How it works
The tool first parses your markup as JSON and reports the exact position of any syntax error. It then checks for @context and @type, verifies the properties Google requires for that schema type, flags recommended properties that are missing, and warns about empty values or placeholder text left in by mistake. Everything runs in your browser — nothing is uploaded.
