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 Export

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