Failed to load XLSX file with Aspose Cells 19.6 .NET

Aspose.Cells Product Family

Hi,

I’m trying to do some tests with Aspose Cells, but have a problem with a XLSX file.

My samples code:

string inputFile = "sample.xlsx";
string outputFile = "output.xlsx";
try
{
    var options = new Aspose.Cells.LoadOptions(LoadFormat.Xlsx);
    var doc = new Workbook(inputFile, options);
    doc.Save(outputFile, SaveFormat.Xlsx);
}
catch(Exception e)
{
string errorMsg = e.Message;
}

When trying to load the sample file as XLSX format, I got an exception: “Object reference not set to an instance of an object.”

I’m using Aspose Cells NET 19.6 and here is my samle: sample.zip (219.7 KB)

Please check and give me feedback about this problem.

Thank you

@dunghnguyen,

Thanks for template file and sample code segment.

After an initial test, I am able to reproduce the issue as you mentioned by loading your template file via Aspose.Cells APIs. I found an exception “Object reference not set to an instance of an object” when loading the XLSX file:
e.g
Sample code:

var doc = new Workbook(inputFile);
