Excel to PDF - Hidden formula is made visible


I have a use case in which I have to export complex Excel files with many formulas.
It is expected that sometimes some formulas are in error, but columns size and margins have been set-up so that errors won't be printed.
Using a PDF printer, or saving as PDF using Excel works like a charm.
Using Aspose.Cells make the error appear.

Please find attached:
1. A very simple example Excel file
2. The PDF generated with Excel
3. The PDF generated with Aspose
4. A snapshot indicating what goes wrong

For your info, this is the C# code used to generate the PDF file:

class Program
static void Main(string[] args)

string inputFilePath = @"\..\..\Files\REF test.xlsx";
string outputFilePattern = @"\..\..\Files\REF test - Saved as pdf with Aspose.pdf";

using (MemoryStream inputStream = new MemoryStream(File.ReadAllBytes(Directory.GetCurrentDirectory() + inputFilePath)))
using (MemoryStream PDFStream = new MemoryStream())
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook(inputStream);
workbook.Save(Directory.GetCurrentDirectory() + outputFilePattern, Aspose.Cells.SaveFormat.Pdf);


Could you help me ?


Thanks for the template file and sample code.

After an initial test, I observed the issue as you mentioned by converting your template file to PDF file format. I found that the hidden formula is made
visible a bit to paste its calculated value in the output PDF file format. I have logged a ticket with an id “CELLSNET-43108” for your issue. We will look into it soon.

Once we have any update on it, we will you know here.

Thank you.
