Thanks for your patience.

We have further investigated the logged issue and according to our findings, all files are saved in Excel 2003 XML Format and in last versions of MS Excel, mentioned warning is appeared, if file extension is “xsl”. To avoid the warning, please, save the document with “xml” file extension:

document.save("C:\\Pdf\\test161\\EmptyPdf.xml", excelsave);

In case of any further query, please feel free to let us know.
