Schema Validator

  • Browser-based
  • No signup

Browser-based

Paste page HTML or raw JSON-LD to find script blocks, validate JSON syntax, and flag missing @context or @type properties.

How to use this tool

1. Paste page HTML or a JSON-LD script block. 2. Run validation to list each block and any errors or warnings. 3. Fix invalid JSON or missing @context/@type before deploying.

Worked example

Example: a Product schema missing @context triggers a warning so you can add "https://schema.org" before publishing.

How it works

Paste HTML or raw JSON-LD to extract structured data blocks and validate JSON syntax, @context, and @type fields for common schema issues.

Limitations

Validation checks JSON-LD syntax and common fields. It does not verify rich-result eligibility with Google.
