FAQ

What does this schema tool generator output?

It outputs JSON-LD structured data, optionally wrapped in a script tag ready to paste into HTML.

Does this tool validate schema like Google’s Rich Results Test?

No. It does basic field checks and generates valid JSON, but it’s not a full search-engine validator.

How do I add advanced properties not shown in the form?

Use Extra properties (JSON) to merge in additional keys (for example, aggregateRating, geo, or areaServed).

Can I generate FAQ schema from plain text?

Yes. Use the FAQPage type and enter blocks with Q: and A:, separated by a blank line.

What format should breadcrumbs use?

One item per line as Label | URL. The tool converts them into a BreadcrumbList with positions.

Is my data sent to a server?

No. The generator runs fully in your browser and does not make network requests.

Should I minify JSON-LD before publishing?

Minified and pretty JSON-LD work the same; minify is mainly for compact CMS fields and easier copying.
