But in newer versions of Microsoft Word you can set documents to be opened in full screen reading mode which makes it look like you're reading real multipage document or book.

File Extension XLS

The easiest way to transform Excel file into presentation is by copying parts of its content (Charts, Tables, Graphs) into PowerPoint presentation.
