Sometimes, you may need to work with workbooks that were created in earlier versions of Microsoft Excel, such as Excel 2003 or Excel 2000. When you open these kinds of workbooks, they will appear in Compatibility mode.
Compatibility mode disables certain features, so you'll only be able to access commands found in the program used to create the workbook. For example, if you open a workbook created in Excel 2003, you can only use tabs and commands found in Excel 2003.
In the image below, the workbook has opened in Compatibility mode. You can see that the sparklines and slicers features have been disabled.
Disabled commands in Compatibility mode
In order to exit Compatibility mode, you'll need to convert the workbook to the current version type. However, if you're collaborating with others who only have access to an earlier version of Excel, it's best to leave the workbook in Compatibility mode so that the format will not change.
To Convert a Workbook:
If you want access to all of the Excel 2010 features, you can convert the workbook to the 2010 file format.
Note that converting a file may cause some changes to the original layout of the workbook.
- Click the File tab to access Backstage view.
- Locate and select Convert command.
Converting the workbook to the newest file type
- The Save As dialog box will appear. Select the location where you wish to save the workbook, enter a file name for the presentation, and click Save.
Saving a new version of the workbook
- The workbook will be converted to the newest file type.
