 ## Enable and Disable Calculation
 
 To perform calculation in an Excel workbook, it is recommended to invoke [EnableSheetCalculations](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html#Syncfusion_XlsIO_IWorksheet_EnableSheetCalculations) method of [IWorksheet](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html). Enabling this method will initialize [CalcEngine](https://help.syncfusion.com/document-processing/excel/excel-library/net/working-with-formulas#calculation-engine) objects and retrieves calculated values of formulas in a worksheet.
