Why the values of cells containing formulas are set to 0 while viewing in viewer?

XlsIO does not have its own calculation engine. So, if you set a formula "=SUM(A2,A4)", the result of the formula cannot be retrieved. We just put the formula into the Excel file. When MS Excel opens the file, it will automatically calculate the formulas. But if you view the file in a viewer, it does not calculate the result of the formula.
