It is quite simple to convert any file to pdf.
I use pdf995 software to convert files to pdf format. http://www.pdf995.com
Just go to the print option (Ctrl+P) and select pdf995 as the printer then hit print and document will be converted to pdf. Save it as you want.
It works with Excel too.
I always used PDF Creator before I got a newer version of office. Install it, then go to print, select the PDF printer (like the XPS printer), and after you select print it will prompt you for a file name and save location.
