About this tool
Parses JSON and checks an object-form type. For a record, it checks the presence of a name, a fields array, and each field’s name and type. It does not resolve named types, check nested schemas, enum symbols, defaults, unions or schema compatibility. A passed basic check does not establish a valid Avro schema.
Everything is generated on your device with nothing uploaded. Your input never leaves the page, and no account or install is required.
