I am not sure what your question is about. Your middle para seems to suggest that you simply want to open the file in Excel and the use the File-Save As menu command to save as HTML or XML. If so, then this has nothing to do with perl, and it has worked for me, even for quite complex worksheets. Actually I used File-Save for Web-HTML format. If as you say,

...but we are having an issue when trying to view the Excelsheet on the web page the display is not quiet right

you need to explain what doesn't display quite right.

If on the other hand, there is some perl involved here, please explain once again, exactly how what would you like done, and how?
