One task, zero friction: validate & generate json-ld structured data — audit any url's schema against google rich-results rules, edit it live, or build new markup for 15+ types with a readiness score.

With nothing to install, an unexpected one-off job takes no longer to start than your regular routine.

It also serves people looking for schema validator, structured data testing tool, and rich results test: the same tool, the same instant results, with nothing locked behind an account or upgrade prompt.

Schema Validator is a free browser-based tool designed to help you validate & generate json-ld structured data — audit any url's schema against google rich-results rules, edit it live, or build new markup for 15+ types with a readiness score quickly and accurately. Whether you are using it for the first time or rely on it daily, this guide covers everything you need to know to get the most out of the tool and its features.

Getting started with Schema Validator is straightforward. The tool runs entirely in your web browser, which means there is nothing to download, install, or configure. Simply open this page, upload your file or paste your data into the work area, and you are ready to go. The interface is designed to be intuitive, with clearly labeled inputs and a single action button to start processing.

For the best results with Schema Validator, pay attention to the configuration options above the work area. Depending on the type of task, you may be able to adjust output format, quality settings, processing mode, or other parameters. These options give you control over the final result so you can tailor the output to your exact requirements without needing a separate editing step.

Privacy is built into how Schema Validator works on ToolsMonk. Because all processing happens locally on your device using client-side JavaScript, your files and data never leave your browser. Nothing is uploaded to any server during or after processing, which makes this tool safe for sensitive documents, personal data, and confidential work files.

Schema Validator is part of the SEO Tools collection on ToolsMonk, which means it works alongside dozens of related tools in the same category. If your workflow involves multiple steps — such as converting a file, processing it, and then converting the result to another format — you can move between tools without leaving the platform or re-entering your data.

If you encounter any issues while using Schema Validator, try refreshing the page and attempting the operation again. Because the tool runs in your browser, clearing your cache or trying a different browser can resolve most common problems.
