What data format does the Calculation Procedure Simulator use for its Input and Output datasets?

• A. XML
• B. JSON
• C. CSV
• D. YAML

Answer: (B)

JSON is used because the Calculation Procedure Simulator needs a lightweight, flexible way to represent input and output data that can easily express nested structures and multiple records. It supports objects with key-value pairs, arrays, and nesting, which fits how datasets are defined—inputs as named fields, with possible lists or nested objects, and outputs that mirror that structure. It’s language-agnostic and widely supported, making serialization and deserialization straightforward in Salesforce tools and external integrations. In comparison, XML tends to be more verbose, YAML is less commonly integrated in Salesforce tooling, and CSV can't capture hierarchical data or complex schemas, so JSON is the practical choice for these datasets.
