Calculation mode options

Refer to the following example code to learn how to modify the calculation mode option. The calculation mode option changes the behavior of MS Excel and SpreadJS. Setting the CalculationMode as "Manual" will prevent MS Excel or SpreadJS from automatically calculating. Additionally, setting CalculationMode to "Manual" improves the speed of opening workbooks that contain a large number of formulas in MS Excel and SpreadJS. The example code demonstrates changing the calculation mode to "Manual," where formulas are not automatically calculated when opening exported XLSX files in MS Excel.
