@vedpathakpranit Thank you for additional information. Unfortunately, I cannot reproduce the problem on my side. Also, HHTML you have provided does not look like HTML produced by Aspose.Words. Here is HTML produced by the following simple code on my side:
Document doc = new Document("C:\\temp\\Sample.docx");
HtmlSaveOptions opt = new HtmlSaveOptions();
opt.setPrettyFormat(true);
doc.save("C:\\Temp\\out.html", opt);
output:

<meta http-equiv="Content-Style-Type" content="text/css" />
