JSON-LD Validator
One missing comma breaks an entire schema block, and the failure is silent. Paste any JSON-LD here and this validator checks the syntax, finds every @type, and confirms the context is present — before you publish.

How to use the JSON-LD Validator
- Paste your JSON-LD, with or without the surrounding script tags.
- Adjust any optional settings to match your page, business or campaign.
- Click the button to generate your result instantly — nothing is uploaded; the tool runs in your browser.
- Copy the result, or download it as a file where that option appears, and paste it into your site, document or campaign.
Frequently asked questions
What does this check?
Valid JSON syntax, the presence of @context and @type for each item, including items inside an @graph.
What does it not check?
Whether you have every property Google requires for a specific rich result — use the Rich Results Test on the live page for that.
Why does my schema parse but not show rich results?
Rich results also depend on the content being visible on the page, the page being indexed, and Google choosing to show them — valid code is only the first step.
