Saving a XLTX or XLTM file makes the file invalid

Customer PO# 110106

I open an existing XLTX or XLTM file, edit it, then save it.

Then when I open it in Excel, I get an error message that says "Excel cannot open the file 'filename' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."

XLT works fine. The Aspose.Cells.dll I have is 5.2.2.0 from Jan 20, 2011.

Thanks,

Eric

Thank you.

Included is the XLTX file that only has text on one sheet.

I removed all code that would manipulate the file, so all I am doing is:

Workbook workbook = new Workbook(filePath);

workbook.Save(filePath);

After an initial test, I can find the issue as you have mentioned opening the re-saved file into MS Excel 2007. I have logged your issue into our issue tracking system with an id: CELLSNET-23969. We will figure your issue soon.

Thank you.
