Structured data
JSON-LD Double-Escape Checker
Google now runs a single pass of HTML unescaping. Paste a URL or your page source and see whether any structured data breaks, and exactly how to fix it.

How it works. The checker finds every application/ld+json block, runs one HTML unescape pass the way Google now does, then parses it. A block that no longer parses is a severe break (no rich results); a block that parses but has garbled values is a minor issue.
One limit. The URL fetch reads the HTML your server returns. If your schema is injected by JavaScript, use the paste box with your browser's rendered source instead.
