Which file type can define available values and options when adding reusable objects?

The correct file type that can define available values and options when adding reusable objects is a spreadsheet. In software like Siemens NX, spreadsheets are commonly used to organize and manage data in a tabular format, making it easy to define various parameters, options, and values systematically.

Spreadsheets can store multiple rows and columns of data, allowing users to present a wide range of choices and configurations for reusable objects. This structured layout supports quick adjustments and easy updates to the data set, facilitating a more efficient workflow when creating and managing reusable components in CAD.

While other file types have their specific use cases, they do not inherently provide the same level of structured data representation and ease of manipulation that spreadsheets offer in this context. For instance, mathematical formulas are primarily for computations rather than data organization, text files generally serve as simple document storage without structured data representation, and XML files are better suited for data interchange rather than direct usability for defining options in a reusable way. Thus, the spreadsheet stands out as the best choice for defining available values and options in this scenario.
