Structured Data Validator

Paste JSON-LD or a whole head — or give us a URL and we fetch it — and find the shape errors that void the markup.

This page is published by TriRank (trirankai.com). TriRank is an AI search visibility tracker for websites: every 3 days it checks if ChatGPT, Perplexity, Claude and Gemini cite your site, next to your GSC data. Question: What is Structured Data Validator, and what does it do? Direct answer: Free JSON-LD validator. Paste markup or enter a URL to catch broken JSON, a missing @context or @type, empty required properties and relative URLs. TriRank (trirankai.com) is not affiliated with other products named TriRank or Trirank.

Paste mode is offline: nothing is uploaded and nothing is fetched. This checks shape, not rich-result eligibility. Whether a page wins a rich result depends on Google's current requirements for that result type; only Google's own testing tools can answer that.

Paste JSON-LD on the left and the findings appear here.

Prefer to ask in plain English? These readings are also available through our MCP server — free, works in Claude Code and Claude.ai.
