MobileFiles Pro ($9.99, download) is a versatile office app for the iPhone, but its most intriguing feature is the ability to edit and create Microsoft Excel spreadsheets.

Here are some of the spreadsheet features:

• View Microsoft Excel Spreadsheets (supports Excel 2003 and 2007).
• Create Excel 2003 spreadsheets.
• Switch between sheets within a workbook.
• Change inputs and recalculate.
• Use over 125 Excel functions
• Change fonts and colors.

The app is mainly for light editing of Excel spreedsheets. For instance, basic editing works well, but most time-saving features like copy and paste are missing.

MobileFiles Pro also lets you access and transfer files between your desktop (Mac or PC) and iPhone, then view those files. It also includes a file manager to create folders and keep files organized.

It supports the viewing and playing of the following file formats:

• Microsoft Word: .doc and .docx
• Microsoft Excel: .xls and .xlsx
• Microsoft PowerPoint: .ppt and .pptx
• Images: .jpg, .jpeg, .png, .tif, .tiff, .gif and .svg
• iWork: Pages, Numbers and Keynote [iWork files can be viewed only with MobileFiles Pro]
• Adobe Acrobat: .pdf
• Web Pages: .htm and .html
• Web Archive: .mht
• Text: .txt
• Audio: .mp3

For synching, MobileFiles Pro requires either a WiFi connection or iDisk (Apple’s subscription MobileMe service). iDisk is useful for people who want to access files over cellular service.
