We are converting HTML to word doc and then again converting back word doc to html. Initially HTML contains <h1> tag but after converting to word doc and then to HTML it is converted into <p> tag.

@atulpandey34 Aspose.Words imports <h1> - <h6> as a paragraphs with the corresponding Heading style in MS Word document. For example see the following HTML:

<html>
<body>
    <h1>Heading 1</h1>
    <h2>Heading 2</h2>
    <p>Regular paragraph</p>
</body>
</html>

After conversion to DOCX, it will look like this:

<w:p>
	<w:pPr>
		<w:pStyle w:val="Heading1" />
		<w:keepNext w:val="0" />
		<w:keepLines w:val="0" />
		<w:spacing w:before="0" w:after="322" />
		<w:rPr>
			<w:b />
			<w:bCs />
			<w:sz w:val="48" />
			<w:szCs w:val="48" />
		</w:rPr>
	</w:pPr>
	<w:r>
		<w:rPr>
			<w:rFonts w:ascii="Times New Roman" w:eastAsia="Times New Roman" w:hAnsi="Times New Roman" w:cs="Times New Roman" />
			<w:i w:val="0" />
			<w:color w:val="auto" />
		</w:rPr>
		<w:t>Heading 1</w:t>
	</w:r>
</w:p>
<w:p>
	<w:pPr>
		<w:pStyle w:val="Heading2" />
		<w:keepNext w:val="0" />
		<w:keepLines w:val="0" />
		<w:spacing w:before="299" w:after="299" />
		<w:rPr>
			<w:b />
			<w:bCs />
			<w:sz w:val="36" />
			<w:szCs w:val="36" />
		</w:rPr>
	</w:pPr>
	<w:r>
		<w:rPr>
			<w:rFonts w:ascii="Times New Roman" w:eastAsia="Times New Roman" w:hAnsi="Times New Roman" w:cs="Times New Roman" />
			<w:i w:val="0" />
			<w:color w:val="auto" />
		</w:rPr>
		<w:t>Heading 2</w:t>
	</w:r>
</w:p>
<w:p>
	<w:pPr>
		<w:spacing w:before="240" w:after="240" />
	</w:pPr>
	<w:r>
		<w:t>Regular paragraph</w:t>
	</w:r>
</w:p>

When you convert the MS Word document to HTML the paragraphs with Heading style applied are exported as <h1> - <h6>, so <h1> - <h6> are roundtripped by Aspose.Words. Here is a simple code I have used for testing:

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

And here is the output:

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta http-equiv="Content-Style-Type" content="text/css" />
    <meta name="generator" content="Aspose.Words for .NET 23.2.0" />
    <title></title>
</head>
<body style="font-family:'Times New Roman'; font-size:12pt">
    <div>
        <h1 style="margin-top:0pt; margin-bottom:16.1pt; font-size:24pt"><span>Heading 1</span></h1>
        <h2 style="margin-top:14.95pt; margin-bottom:14.95pt; font-size:18pt"><span>Heading 2</span></h2>
        <p style="margin-top:12pt; margin-bottom:12pt"><span>Regular paragraph</span></p>
    </div>
</body>
</html>

As you can see <h1> and <h2> are preserved after roundtrip.

Could you please attach your source HTML here for testing? We will check it and provide you more information.
