Why a JSON-LD block fails to parse

JSON-LD must be strict JSON. The usual breakages are a comma after the last property, curly quotes inserted by a content editor or word processor, an unescaped double quote inside a product description, and a template that prints nothing where a value was expected, leaving "price": ,. Copy the failing block into the JSON formatter to find the exact position, or repair it with the JSON repair tool and then fix the template that produced it.

After it parses

A valid block still has to describe what is visible on the page: search engines ignore or penalise markup for reviews, prices, or FAQs that visitors cannot see. Each rich result type also has required properties, such as name and a price or rating for a product.

Google's Rich Results Test checks eligibility for Google's features, and the Schema.org validator checks the vocabulary in general. Use them after this tool has confirmed that every block is found and parses.

How to use it

1. Paste a public page URL.
2. Choose “Inspect schema.”
3. Open each detected block and review any parse errors.
