Which file format is typically used for configuration settings in SFCC?

In Salesforce Commerce Cloud (SFCC), the commonly used file format for configuration settings is JSON. This choice is appropriate because JSON (JavaScript Object Notation) provides a lightweight and easily readable format that is well-suited for structured data representation, making it highly accessible for developers working within the SFCC framework.

JSON allows for nesting of data, which is useful for complex configurations that need to include multiple levels of settings or parameters. It is also easily parsed and generated by JavaScript, which is the primary language used in SFCC development. This enhances the integration and implementation of configuration settings within the platform, where JavaScript is frequently utilized.

Other formats like XML, CSV, and YAML each serve their own purposes but are less common for configuration in SFCC. XML is more verbose and primarily used in different contexts, CSV is typically used for tabular data rather than hierarchical configuration, and YAML, while human-readable and useful for configurations in other contexts, is not the standard in SFCC development.
