Converting a DOCX to HTML and convert it back to DOCX changed table margin value


When I converted a DOCX (not in compatibility mode) to an HTM file using Aspose.Words, then converted it back to DOCX. I noticed the DOCX became in compatibility mode and margin value was changed unexpectedly.

var doc = new Document(@".\test.docx");
var htmlSaveOption = new HtmlSaveOptions();
htmlSaveOption.AllowNegativeIndent = true;
doc.Save(@".\out.htm", htmlSaveOption);
var htmlDoc = new Document(@".\out.htm");

The negative margin value was -0.5cm in the original document, but it became -0.3cm in the final document.

I’ve attached the test files and a screenshot for your reference. Could you please help me check?

Please use the following code to fix this issue:

Document doc = new Document("E:\\test\\test.docx");
var htmlSaveOption = new HtmlSaveOptions();
htmlSaveOption.AllowNegativeIndent = true;
doc.Save("E:\\test\\19.2.htm", htmlSaveOption);

var htmlDoc = new Document("E:\\test\\19.2.htm");
OoxmlSaveOptions opts = new OoxmlSaveOptions(SaveFormat.Docx);
opts.Compliance = OoxmlCompliance.Iso29500_2008_Transitional;
htmlDoc.Save("E:\\test\\19.2.docx", opts);
