Incorrect Workbook Calculation

Aspose.Cells Plugin Family
1

Hi- I have a complicated workbook available at the link I share below. When I call the code below to calculate the workbook I am finding a very clear incorrect result in cell P1_xReturns_MS!C76. The Aspose.Cells calculation results in an incorrect value of 0.00% while Excel correctly calculates the cell to be 35.00%.

Here’s the simple code used to calculate the workbook. I am using Aspose.Cells 25.6:

            Aspose.Cells.Workbook wbk = new Aspose.Cells.Workbook(<Enter path and filename>);
            wbk.Settings.FormulaSettings.EnableCalculationChain = true;
            Aspose.Cells.CalculationOptions AsposeCalculationOptions = new Aspose.Cells.CalculationOptions()
            {
                Recursive = true,
                IgnoreError = false,
            };
            wbk.RefreshDynamicArrayFormulas(true, AsposeCalculationOptions);
            wbk.CalculateFormula(AsposeCalculationOptions);

Here’s a link to my file: https://drive.google.com/file/d/1LlfI-iBzHwoswA78ozkhthi0V-W0oNsP/view?usp=sharing

Please confirm that you’re also getting the incorrect result and review for a potential bug.

Note, if I don’t include the EnableCalculationChain = true line, this calculation error does not occur. However, I am re-using this workbook for multiple calculations and want to use this option. The bug appears to be in the calculation chain.

@mattgabriel,

Thanks for the template XLSM file and details.

I tested your scenario/case and was able reproduce the issue as you mentioned by using your template XLSM file and following sample code snippet. I found incorrect workbook (formula) calculations when EnableCalculationChain = true. If I don’t enable the formulas calculation chain, it works fine.

Aspose.Cells.Workbook wbk = new Aspose.Cells.Workbook("e:\\test2\\Swift_v4_FAS_GDC_EBMS_v2_Azure20250718160737_NoFxact.xlsm");
// If I comment this line, the formula is calculated correctly
wbk.Settings.FormulaSettings.EnableCalculationChain = true;

Worksheet ws = wbk.Worksheets["P1_xReturns_MS"];
Aspose.Cells.Cell cell = ws.Cells["C76"];
Console.WriteLine(cell.StringValue);//35.00%

Aspose.Cells.CalculationOptions AsposeCalculationOptions = new Aspose.Cells.CalculationOptions()
{
                Recursive = true,
                IgnoreError = false,
};
wbk.RefreshDynamicArrayFormulas(true, AsposeCalculationOptions);
wbk.CalculateFormula(AsposeCalculationOptions);
Console.WriteLine(cell.StringValue);//0.00% - Not Ok
