Your editing tools are limited compared to what you get in desktop productivity suites for Mac and PC — especially the real Microsoft Office suite — but the basic formatting tools in this iPad app will be enough for the vast majority of on-the-go edits that most users are likely to want to make.
Tips
You can open Microsoft Office documents that are macro-enabled as read-only files, but you can’t edit them. If you plan to edit your Office files on your iPad, be sure to use the common file formats (DOC, DOCX, TXT, XLS, XLT, and XLTX).
Another nice feature is the Multi-Edit Toolbox, which allows you to make several changes at one time to selected text (font, size, color, and paragraph formatting).
