Worksheet.CodeName Property (Excel)
Returns the code name for the object. Read-only String .
expression An expression that returns a Worksheet object.
The value that you see in the cell to the right of (Name) in the Properties window is the code name of the selected object. At design time, you can change the code name of an object by changing this value. You cannot programmatically change this property at run time.
The code name for an object can be used in place of an expression that returns the object. For example, if the code name for worksheet one is "Sheet1", the following expressions are identical:
It's possible for the sheet name to be different from the code name. When you create a sheet, the sheet name and code name are the same, but changing the sheet name doesn't change the code name, and changing the code name (using the Properties window in the Visual Basic Editor) doesn't change the sheet name.
This example displays the code name for worksheet one.
