Reading from xls or xlsx - with style

[Ben Rubinstein]

I'm aware that there are a couple of libraries floating around for reading 
Excel documents - do any of them allow the formatting of runs of text within 
cells to be read? I want to import some data where some of the text in a cell 
may contain some parts which are in italics or bold. Are there existing 
libraries that support this use?

Many thanks,

Ben
