# ConvertJSONToDocuments

Many systems can output data in JSON format. The ConvertJSONToDocuments processor detects any FlowFile that represents a JSON file and attempts to parse the JSON into Knowledge Discovery documents. The processor produces a new FlowFile for each document. If an input FlowFile does not represent a file in JSON format, the processor transfers the FlowFile to the "unprocessed" relationship.

## Properties

Name | Default Value | Description
--- | --- | ---
IDOL License Service |  | An IdolLicenseServiceImpl that provides a way to communicate with a Knowledge Discovery License Server.
Document Registry Service |  | A DocumentRegistryServiceImpl controller service that manages and updates a document registry database. This ensures that documents are indexed in the correct order.
JSON Parsing Config |  | A collection of configuration parameters that configure JSON Parsing. The parameters that you can use are the same as those in the `[JSONParsing]` section of the CFS configuration file. (In the NiFi processor configuration, do not include the `[JSONParsing]` section header). For more information about these parameters, refer to the Connector Framework Server Reference.
Commit Batch Size | 100 | The processor outputs documents in batches to limit memory use and allow subsequent tasks to begin processing the documents sooner. This property specifies the maximum batch size.

## Relationships

Name | Description
--- | ---
extracted | New FlowFiles (individual Knowledge Discovery documents that were extracted).
failure | Original FlowFiles that represent a JSON file, but resulted in parsing errors.
processed | Original FlowFiles that represent a JSON file, and were parsed successfully. Original FlowFiles are routed to this relationship when they contain valid documents.
unprocessed | Original FlowFiles that do not represent a JSON file.
