Aspose failure converting a particular xls to pdf

The attached xlsx file fails to save to pdf when using the code below in c#

Aspose.Cells.Workbook book = new Aspose.Cells.Workbook("TestFile.xlsx");

I believe the error is happening on the first line of code there. The initialize of the workbook. And the error thrown is System.FormatException

The same code works fine for other .xlsx files.

This is using the Aspose.Cells.dll versioned


Thanks for the template file.

After an initial test, I observed the issue as you mentioned by loading your template XLSX file via Aspose.Cells APIs. I found an exception: “Input string was not in a correct format” when loading the XLSX file format:
Sample code:

Aspose.Cells.Workbook book = new Aspose.Cells.Workbook(“e:\test2\TestFile.xlsx”);
