Schema Validator
Validate JSON-LD structured data, inspect common schema fields, and pretty-print valid output.
This tool validates JSON syntax and inspects common schema properties such as @context and @type. It does not call external validators.
| Metric | Value |

Privacy: validation runs locally in your browser. No schema content is stored or transmitted.
How it works
Paste JSON-LD into the input area and validate it. If the syntax is valid, the tool pretty-prints the JSON and inspects key fields.
It is useful as a local pre-check before testing in external search-engine-specific tools.
Examples
- Valid object → schema object with
@contextand@type - Valid array → multiple schema objects in one JSON array
- Invalid JSON → shows parse error and does not output formatted JSON

FAQ
- What does this schema validator check?
It checks whether the JSON-LD is valid JSON and whether common schema properties such as @context and @type are present.
- Does it guarantee Google rich results support?
No. It validates syntax and basic structure only. Rich results eligibility depends on more specific requirements.
- Can it validate arrays of schema objects?
Yes. It can parse JSON arrays as long as the JSON syntax is valid.
- Is my schema stored?
No. Everything runs locally in your browser and is not transmitted.
