How to use JSON Schema Validator

Paste your schema and your data in the two panels; the validator reports whether the data conforms and lists each violation.

Frequently asked questions

Which schema draft is supported?

JSON Schema draft-7, the most widely adopted version for validating types, required fields and value constraints.

What errors does it report?

Each failing keyword — such as type, required, minimum or pattern — is reported with the JSON path where it occurred.

Is my data uploaded?

No — validation runs entirely in your browser, so both the schema and the data stay on your device.
