+### Output Format
+
+By default, the Aptible CLI outputs data as unstructured text, designed for human consumption.
+
+If you need to parse the output in another program, set the `APTIBLE_OUTPUT_FORMAT` environment variable to `json` when calling the Aptible CLI for JSON output.
+
+The default format is `text`.
