Schema Markup Checker

Why Use a Dedicated Website Schema Checker?

Structured data is the backbone of modern SEO – it helps search engines understand your content and display rich results. But even small errors can break your markup. Our schema checker gives you a clear, detailed view of every @type and property embedded in your code, so you can catch issues before they impact your rankings. Unlike online validators that send your data to external servers, this tool works entirely offline, ensuring your sensitive code stays private.

How Our Google Schema Validator Alternative Works

Google’s own validator is excellent, but sometimes you need a quick second opinion or want to test drafts without connecting to the web. Our tool acts as a perfect complement:

• Paste any HTML – from a live page, a local file, or a development environment.

• Click “extract all schema” – we parse the code and list every schema type found.

• Review the output – see JSON‑LD blocks, microdata items, and RDFa in a clean, organized layout.

It’s like having a schema markup checker  right on your desktop, but without the need for an internet connection.

Key Features of This Schema Checker

• Dual‑format support – Detects JSON‑LD, Microdata, and RDFa in one pass.

• Comprehensive type extraction – Lists every @type from JSON‑LD and every itemtype from microdata.

• Instant previews – Shows a snippet of the data for quick verification.
