First, you need to parse HTML to recognize relationships between the elements
<table>,
<tr> and
<td> and extract the HTML content from
<td>. If you can assume your HTML is a well-formed XML, this is easy; you can use one of available XML parsers.
Here is a short review of XML parsing capabilities you can use:
- Use
System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^]. - Use the class
System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
See http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^]. - Use the class
System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].
If you cannot assume well-formed XML on input, this is of course more difficult. You can use some HTML parser which can handle such input. Try, for example, this one:

To create Excel document you need to use Microsoft Office interop. Start here:
