This section describes how to define a file connection and upload a JSON schema for an input file. To define an output JSON file connection and schema, see Setting up JSON metadata for an output file.

Now you can drag and drop the file connection or the schema of it from the Repository tree view onto the design workspace as a new tFileInputJSON or tExtractJSONFields component or onto an existing component to reuse the metadata. For further information about how to use the centralized metadata in a Job, see Using centralized metadata in a Job and Setting a repository schema in a Job.

To modify an existing file connection, right-click it from the Repository tree view, and select Edit JSON to open the file metadata setup wizard.

To add a new schema to an existing file connection, right-click the connection from the Repository tree view and select Retrieve Schema from the contextual menu.

To edit an existing file schema, right-click the schema from the Repository tree view and select Edit Schema from the contextual menu.
