File formats that are supported in Excel
You can save a Microsoft Office Excel 2007 file in another file format by clicking the Microsoft Office Button  , and then clicking Save As. The file formats that are available in the Save As dialog box vary, depending on what type of sheet is active (a worksheet, chart sheet, or other type of sheet). You can open a file that was created in another file format (in an earlier version of Microsoft Office Excel or in another program) by clicking the Microsoft Office Button , and then clicking Open. You will be prompted to save it to an Office Excel 2007 format, unless you open a workbook that is shared. For files that were created in an earlier version of Excel, you have the option to keep the original format. Note Whenever you save a file in another file format, some of its formatting, data, and features may be lost. For more information, see Formatting and features that are not transferred in Excel file format conversions. In this article

Tips for file formats that are not supported by ExcelIf a file format that you want to use is not supported in Excel, you can try the following: - Search the World Wide Web (WWW) for a company that makes file format converters for file formats that are not supported in Excel.
- Save to a file format that another program supports. For example, you may want to import your spreadsheet into another program that does not support the Excel file format. But the other program may be able to import another supported file format, such as an XML spreadsheet or a text file format. In this case, you can save your workbook to the XML spreadsheet format, and then from the other program, import the XML file.
