The Compatibility Checker identifies
the potential loss of functionality when you save an Excel workbook in
the Excel 97-2003 Workbook file format. The Compatibility Checker
generates a report that provides a summary of the potential losses and
the number of occurrences in the workbook. You can also specify what
versions to show compatibility issues. Use the report information to
determine what caused each message and for suggestions on how to change
it. If the loss is due to a new feature in Excel 2013—such as new
functions, custom layouts or Quick Styles applied to shapes, pictures,
and WordArt—you might be able to simply remove the effect or feature.
In other cases, you might not be able to do anything about it. To
maintain a visual appearance, SmartArt graphics and other objects with
new effects are converted to bitmaps to preserve their overall look and
cannot be edited.
