What format is primarily used to represent data in OmniStudio?

OmniStudio primarily uses JSON (JavaScript Object Notation) to represent data. This choice is correct because JSON is lightweight, easy to read and write for humans, and easy to parse and generate for machines. It has become the standard format for data interchange, particularly in web applications, due to its simplicity and versatility. JSON's structure supports nested data and arrays, making it highly effective for the complex data structures often used in OmniStudio applications.

In contrast, while formats like CSV (Comma-Separated Values) are used for flat data representations and are suitable for simpler datasets, they lack the hierarchical structure that JSON provides. XML (eXtensible Markup Language) is another format that supports complex data representations, but it tends to be more verbose and less efficient for parsing compared to JSON. YAML (YAML Ain't Markup Language) is also used for data serialization, but it is less commonly employed in the context of OmniStudio as compared to JSON.

Thus, JSON's compatibility with modern web APIs and its effectiveness in data representation within the OmniStudio framework makes it the primary format utilized for conveying data.
