Does a valid result guarantee rich results?

No. Valid JSON-LD with recommended fields is a prerequisite, but rich-result eligibility is decided by the search engine. Always confirm with Google's Rich Results Test for your target result type.

Is my schema sent to a server?

No. Validation runs entirely in your browser. Nothing you paste leaves your device.

What this means

Structured data helps search engines understand your content and can enable rich results. This tool checks JSON validity and common recommended properties — it's a syntax and completeness helper, not a replacement for Google's Rich Results Test, which confirms eligibility for specific rich results.
