What is SD Validator?

Search engines require specific fields for rich-results eligibility. This validator checks required and recommended properties.

How it works

We parse the JSON-LD, verify @context and @type, then check required properties per type against a local Schema.org property map.

  1. Enter your input. Type or paste your input into the field above — the tool responds instantly.
  2. Review the result. Output updates live as you type. Everything runs entirely in your browser.
  3. Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
