[]
Base class for workbook open options.
This abstract class defines the common contract for option objects passed to
workbook open APIs. Concrete subclasses represent format-specific settings for
opening different workbook sources, such as CSV, XLSX, XLSM, XLTX, or SpreadJS
.sjs content.
Each subclass assigns its associated OpenFileFormat through this property and can expose additional settings for its target format. Use FileFormat to inspect the format associated with a concrete options instance.
