Schema Tool
JSON-LD Validator
Paste your JSON-LD to validate, format, and detect schema issues.
How It Works
Using the JSON-LD Validator
The JSON-LD Validator runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full schema audit.
- 1Paste in your URL, text, or data — no signup required.
- 2The tool runs its analysis and returns results in seconds.
- 3Review the flagged issues, ranked by severity, with a plain-English explanation of each.
- 4Fix the highest-priority items first, then re-run to confirm.
Structured data is how search engines and AI answer engines understand what a page actually is, not just what it says. Valid JSON-LD is table stakes for rich results in Google Search and for being cited accurately by AI Overviews, ChatGPT, and Perplexity.
