Product/Offer JSON-LD Preflight
Tools & automationInternal tool
A private offline CLI that checks a limited Product and Offer structured-data profile in JSON or saved HTML and reports clear issue paths.
About the project
Product/Offer JSON-LD Preflight provides a narrow, deterministic check for structured product data. It reports status and issue paths for price syntax, currency-code shape and local Offer references.
The tool is designed as a practical preflight, not a complete structured-data certification system.
