Thanks to Texas Mac Man for pointing to this link.

"Quickoffice Connect Mobile Suite and Documents To Go These two apps share an important feature: unlike Numbers, they can open, edit, and save an Excel spreadsheet without stripping out any data or formatting, even though they can’t display or edit all the existing information; spreadsheets can make the round trip from Mac to iPad and back safely, without losing anything."
