About this tool
Comprehensive documentation & audit utility guideStructured data (JSON-LD) tells search engines what a page is about in a machine-readable way — it's how Google shows rich results like star ratings, recipe cards, or FAQ dropdowns directly in search. This tool extracts every JSON-LD block from a page and checks it's structurally valid.
How it works
1
Choose an input
A live URL, or paste HTML containing JSON-LD script tags.
2
We extract every block
Every <script type="application/ld+json"> tag on the page is parsed.
3
See what's valid
Each block is checked for the required @context and @type fields.
What it checks
Every JSON-LD block present on the page
Whether each block has the required @context and @type fields
The exact parsed structure, so you can see what a crawler would read
