The attractive OfficeSuite Pro lets you view, edit, and create Word, Excel, and PowerPoint docs. Its spreadsheet tool is easy-to-use, although it lacks simultaneous, multiple-cell editing. There’s a function button, plus you can format cells, rows, and columns, and insert charts. Save spreadsheets in different formats, like .xlsx, .xls and .csv. Cloud storage support includes Google Drive, Dropbox, Box, SugarSync and Microsoft SkyDrive.
