Aspose.Cells.SaveFormat.Pdf changes value to "#DIV/0!"

When we convert an Excel tab to PDF, valid numbers in some cells are converted to “#DIV/0!” in the PDF.

I have attached an example Excel spreadsheet. Note that on the tab “Funding Schedule” there are no cells with “#DIV/0!”. In the attached PDF, second page, the converted tab has some “#DIV/0!” values (highlighted in yellow).

This is a .NET environment. Excel 2007, Aspose.Cells.dll= 7.6.0.0, Aspose.PDF.dll = 8.5.0.0.

Thanks for any assistance!

Hi David,

Thank you for using Aspose products.

I have evaluated your presented scenario while using the latest version of Aspose.Cells for .NET 7.7.1.0, and I am able to replicate the said issue. Formula fields are displayed as #DIV/0! when your provided spreadsheet is converted to PDF. An investigative ticket (CELLSNET-42295) has been logged in our bug tracking system to probe further into this matter. Please spare us little time to properly analyze the problem cause, and to provide a fix (if applicable). In the meanwhile, we will keep you posted with updates in this regard.

Please accept our apologies for your inconvenience.

Do you have any ideas why some formulas work and others don’t? Or any suggestions for workarounds?

Thanks.

Hi David,

Sorry for a bit delayed response.

I have worked further with your presented scenario in order to find out a workaround for the time being. Usually, Workbook.CalculateFormula method does the trick to resolve any calculation related scenarios before setting the Workbook to render. In this case it isn’t helping. I have also checked other properties publicly exposed by Aspose.Cells for .NET API, but I am afraid, I am unable to find a solution at this moment.

As discussed earlier, we may take sometime to properly analyze the problem on our end. As soon as we have isolated the problem cause, we will quickly move forward to fix it for you with the next release of Aspose.Cells for .NET API.

Please accept our apologies for the inconvenience caused.

We tried several variations to see if we could work around this, did not succeed.

We did notice that when we replaced N5 in the Funding Schedule tab (which had the formula “=R22”) with a constant value, the “#DIV/0!” cells converted correctly. It is not a workaround, but it might help your analysts.

Thanks.
