Yes, if it's saved in a text format (some or all .xls files are in text format... I haven't tried all versions/formats, so I don't know if all are). Try opening it in Notepad or Wordpad or whatever and see if it's text. If so, you just have to parse it. In at least one format, all tab names are listed at the top and then at each tab, it will show the "code" again for the tab so you know which tab you are on.
