About This Tool
The Schema Validator checks whether pasted JSON-LD is valid JSON, detects @type values, pretty-prints the document, and reviews common required and recommended fields for popular schema types. It supports standalone objects, arrays of objects, and @graph documents.
The field review is a practical local guide rather than a search-engine certification. Rich-result requirements change and can depend on page content, eligibility rules, and policies outside the JSON-LD itself.
ToolPool runs this utility in your browser, so your input stays on your device and is not uploaded to our server.
How To Use This Tool
- 1Paste JSON-LD into the editor or load the sample Product schema.

- 3Pretty-print or copy the formatted schema after making corrections.

Workflow Tips
Schema Validator is designed for quick browser work, but it is still worth reviewing the result before you use it in a live project, client document, public page, or production workflow. Keep an original copy of important source material, compare the output with what you expected, and repeat the task with slightly different settings when quality, formatting, or accuracy matters.
For larger workflows, pair this page with Schema Markup Generator, JSON Validator, JSON Formatter, Meta Tag Generator. Moving between related utilities can save time when you need to clean source data, prepare web assets, create supporting IDs, check calculations, or package output for another system. Internal links also make it easier to stay in one private workspace instead of jumping between several single-purpose sites.
The local processing model helps protect sensitive content because ToolPool does not need to receive your files, text, or form values to complete the task. Good privacy habits still matter after the result leaves the page: avoid pasting unnecessary secrets, check downloaded files before sharing them, and clear the workspace when you are finished on a shared computer.
