The following graphics, object, and ActiveX issues cause a significant loss of functionality:

Issue Solution
Any effects on this object will be removed. Any text that overflows the boundaries of this graphic will appear clipped. In Excel, you can use special effects, such as transparent shadows that are not supported in earlier versions of Excel. The special effects will be removed. Also, in Excel, when you insert text in a shape that is longer than the shape, the text spills outside of the boundaries of the shape. In earlier versions of Excel, this text will be truncated. To avoid truncated text, you can adjust the size of the shape for a better fit.

In the Compatibility Checker, click Find to locate the objects that have special effects applied so that you can remove the special effects as needed.

An embedded object in this worksheet is created in a newer version of Office. You cannot edit it in an earlier version of Excel. Embedded objects that are created in Excel cannot be edited in earlier versions of Excel.
Uninitialized ActiveX controls cannot be transferred to the selected file format. The controls will be lost if you continue. If a workbook contains ActiveX controls that are considered to be Unsafe for Initialization (UFI), they are lost when you save the workbook to an earlier Excel file format. You may want to mark those controls as Safe for Initialization (SFI).

If you open a workbook with uninitialized ActiveX controls that are set to high security, you must first use the Message Bar to enable them before they can be initialized.
