Save specific range of excel sheet as html page

I am trying to save specific range of cells of an excel sheet as a html page. Until now, I am able to save the complete excel file. The output of the complete files contain sheets which I don't require. How can I save specific sheets as a html page?

excel = actxserver('Excel.Application');
xlsfile = 'C:\documents\data.xls';
file = excel.Workbooks.Open(xlsfile);
file.SaveAs('C:\documents\test.htm', 44);

%%Using the following doesn't help with "SaveAs"
% sheet1=excel.Worksheets.get('Item', 'Sheet1');
% range1=get(sheet1,'Range', 'B4:M15');

Any form of help will be appreciated. Thank you.
