The files on our site are provided in a variety of formats. The software you use to view the files depends on the file type. The following general information may help, but because everyone's computer setup is different, we are unable to provide specific assistance.
Note about XLSX format: If you're using Internet Explorer on an older version of Windows, such as XP or Vista, your browser will probably try to download this file type as a ZIP file, which is unusable by Excel or other spreadsheet program. The easiest way to solve this is to use a better browser, such as Firefox, Chrome, or Safari. None of these browsers suffer from this bug, and all will provide a much improved browsing experience.
* To open an XLS or XLSX file, you can use OpenOffice (free, Mac or Windows), NeoOffice (free, Mac only), or a newer version of Microsoft Excel (commercial product, Mac or Windows). Older versions of Excel won't open XLSX files.
