Aspose.Cells corrupting excel document


When opening the attached excel document using aspose.cells (tested with 7…4) and saving it, the saved document cannot be opened with excel anymore.

Used code:

Dim objWorkbook As New Aspose.Cells.Workbook(“c:\temp\savetest.xlsx”)

Excel error when opening the saved excel workbook:
Excel found unreadable content in ‘cellstest_2_modified.xlsx’. Do you want to recover the contents of this workbook? If you trust the soruce of this workbook, click Yes.

I have attached the input and output excel workbooks.

Is this a bug in aspose.cells, and what can we do about this?

Thanks for the files.

I can find the issue as you have mentioned by opening your attached template file and re-saving it. The output file opens fine into MS Excel 2007 but gives error in MS Excel 2010 (e.g "Excel found unreadable content...").

Sample code:

Workbook objWorkbook = new Aspose.Cells.Workbook("e:\\test2\\savetest.xlsx");
