If you have an .xlsx file attachment in your email inbox but the computer has no Office 2007 to open that extension, what are the available options?
The xlsx files is the default extension for spreadsheets written in Microsoft Office Excel 2007. The format is currently not support by GMail attachment viewer or any of the online office suites like Google Docs.
However, you can easily convert .xlsx spreadsheet to the traditional .xls format using the Microsoft Office compatibility Pack available here. This will help you open, edit, and save .xlsx files in Office 2000, Office XP, or Office 2003. More details on Office 2007 FAQ.
Alternatively, you can convert .xlsx to .xls or other text formats online using the Zamzar.com service here. Unlike the Microsoft compatibility pack, the Zamzar .xlsx to .xls conversion services will not require a copy of Microsoft Office on your computer.
