How to use

What is JSON-LD and why is it crucial for Google SEO?

JSON-LD is Google's preferred schema format. It helps search engines parse page context to award rich search result snippets and knowledge panels.

Can this tool extract multiple JSON-LD scripts from one page?

Yes. The extractor scans the DOM for all <script type="application/ld+json"> nodes and displays each formatted JSON block sequentially.

Is my HTML source code kept private?

Yes. DOM parsing is executed client-side inside your browser sandbox without submitting HTML payloads over the internet.
