Returns or sets a boolean indicating whether the Workbook will automatically call its [[Workbook.resumeCalculations]] methods before the Load method returns. When the Load method starts the [[Workbook.suspendCalculations]] is invoked so that no calculations occurs as the load is in progress. When the Load operation is complete and the Workbook is about to be returned from the Load method, it will call the [[Workbook.resumeCalculations]] method to ensure that the loaded formulas have been added to the calculation network and the formulas can be calculated. However if one wanted to delay calling that method, perhaps to add additional formulas to the workbook being loaded, one can set this property to false and then the Workbook will not call ResumeCalculations. Instead it will be the responsibility of the caller to invoke this method.

Returns or sets the value for the [[Workbook.culture]] property.

Returns or sets a boolean indicating whether duplicate formulas parsed during the load will be optimized for faster loading of the workbook.

Gets or sets the Dpi to use when calculating row and column sizes for the workbook. If empty, the system Dpi will be used.

Returns a list of user defined functions that should be registered before the workbook is loaded.
