JSON Schema Validator FAQ
Which JSON Schema draft is supported?
Validation uses Ajv with JSON Schema draft-07, the most widely used draft. The schema generator also emits draft-07.
Can it create a schema for me?
Yes. Paste example JSON and hit "Generate schema" — JRJI infers types, nested properties, required keys and array item schemas from your sample.
Is my data uploaded?
No. Validation and schema generation run entirely in your browser.
