Issues with WORKDAY formula

Hello, I think there is a bug when ASPOSE is using this formula. I have an Excel file containing a formula like this:


Where HOLIDAYS is defined in the excel document as a Range. ASPOSE specifically breaks when it tries to evaluate a date

that is inside the HOLIDAYS range (If the date to be evaluated by the WORKDAY formula is not inside the HOLIDAY range it WON’T fail). I also

tried the following options where ASPOSE will also fail evaluating:

=WORKDAY(C3,-1,H7:M7) —> Using range directly

=WORKDAY(E3,-1,{42729,42730,42736,42737,42795,42788}) —> Using a constant array

The cells in which will fail are C48, D48 and E48 which correspond to the evaluation of 25-Dec-2016 as a HOLIDAY.

The exception is thrown in the following method:

private readonly Workbook _workbook;


As: Error in calculating Cell[[0]Threshold Analysis!C48]

I attach an excel file for you to test.

Hello I tried v17.02.8 (.NET 4.0) and it is not working, I sued the previous attached document, I am having the following error:

Error in calculating Cell[[0]Threshold Analysis!C53]

Not sure about the reason as that cell does not include any day within HOLIDAYS range.



I tested your scenario/ case again with v17.2.8 using your original file with the following sample code, it works fine and and I could not find the issue (no error occurred):
Sample code:

Workbook wb = new Workbook(“e:\test2\ASPOSE_Template.xlsx”);

Please make sure that you are using latest version/fix: Aspose.Cells for .NET v17.2.8. You may print the version number at runtime to get to know you are using the right version:
