@nchauras I do not see issues with your HTML document conversion. I have used the following simple code for testing:

Document doc = new Document(@"C:\Temp\in.html");
doc.Save(@"C:\Temp\out.docx");

Here is output DOCX documents produced by Aspose.Words and MS Word:
ms.docx (12.5 KB)
out.docx (7.2 KB)

Could you please specify what exactly is not retained? Also, please not, Aspose.Words is designed to work with MS Word documents. HTML documents and MS Word documents object models are quite different and it is not always possible to provide 100% fidelity after conversion one format to another.

input html had colored legends like below –

@nchauras Thank you for additional information. In your HTML you use span for inserting such colored rectangles:

<span style="display: inline-block; background-color: rgb(132, 227, 185); height: 5pt; width: 5pt;"></span>

In MS Word document analog of span is Run node that can have background, like you see in the output document, but it cannot have fixed dimension.
If you have control over the HTML creation process, I would suggest you to use images or SVG to insert these colored rectangles. In this case they will look like expected in MS Word.
