Important

Take into account the following when you call this method:

• The operation is not thread safe (the document should not be accessed simultaneously by different threads). Wait until the operation is completed before you continue to work with the document (for example, use the await operator).

Calculate Formulas Before Save Operation

The default calculation mode for a Workbook is Manual. This mode implies that the Spreadsheet does not calculate formulas before it saves a document. Call the Workbook.Calculate or Workbook.CalculateFull method to calculate all formulas in the workbook.
