Save doc template as docx


I have a template in the old word format doc. I use that doing mailmerge with aspose.words.
Now I want to return the result document in docx. This seams to work (extension is corret), but the document opens in compatibility mode… When I try “save as” there is an warning about the new fileformat.

I use the following code to save the document:
response.Document.Save(@“d:\temp(” + Guid.NewGuid() + “).docx”, FileFormatUtil.ExtensionToSaveFormat(“docx”));

What am I doing wrong? I am using the last version of aspose.words.


Hi Adrian,

Thanks for your inquiry. I think, you should just specify OOXMLCompliance:


Here is code example:

Document doc = new Document(@"Test001\in.docx");

OoxmlSaveOptions opt = new OoxmlSaveOptions(SaveFormat.Docx);

opt.Compliance = OoxmlCompliance.Iso29500_2008_Transitional;

doc.Save(@"Test001\out.docx", opt);

I hope, this will help.

Best regards,

Thank you!
