The flows are stored as JSON and there is a setting to save them as prettified to make them more readable (`flowFilePretty: true` in the settings.js which is on by default in recent release).

Also the flow storage is fully plugable (https://nodered.org/docs/api/storage/) so nothing to stop you choosing/implementing a different storage format e.g. YAML https://github.com/natcl/node-red-contrib-yaml-storage
