Not all Excel worksheet functions are supported as methods of the Application object in Visual Basic for Applications

You can write Visual Basic procedures that call Microsoft Excel worksheet functions. The worksheet functions that are available to Visual Basic procedures are in the Application object, and are listed in the
Methods or Properties list for the Application object in the Visual Basic Object Browser.


Most worksheet functions that are not available as methods of the
Application object have an equivalent Microsoft Visual Basic built-in operator or function. For example, the MOD worksheet function is not available as a method of the Application object because there is an equivalent Mod operator built in to Visual Basic. A Visual Basic operator works faster than a Microsoft Excel function in a Visual Basic module.

Excel Worksheet Functions Available as Methods in Visual Basic

NOTE: The following steps assume that you have installed the Visual Basic Help file.


To display a list of all the Microsoft Excel worksheet functions that are available as methods of the Application object in Visual Basic, follow these steps:

1. In the Visual Basic Editor, type worksheet functions in the Microsoft Office Assistant, and then click Search.
   
2. In the list of topics, click List of Worksheet Functions Available to Visual Basic.
   

To locate the equivalent Visual Basic operator or function of a Microsoft Excel worksheet function that is not available as an Application object method, follow these steps:

1. In the Visual Basic Editor, type the function or operator name in the Office Assistant, and then click Search. For example, type mod.
   
2. In the list of topics, click the topic for the function or operator. For example, click the Mod Operator topic.
   

The following table contains worksheet functions that are not available as methods of the Application object. The Visual Basic Equivalent column lists functions you can use that produce results the same as (or similar to) results that the functions return.

                                     referencing cells.
   INFO()                            No direct equivalent - use the
                                     following:
                                     CURDIR function, the following
                                     Application properties (MEMORYTOTAL,
                                     MEMORYUSED, MEMORYFREE, VERSION,
                                     OPERATINGSYSTEM, CALCULATION, COUNT)

   N()                               No equivalent (none needed)
   NA()                              No equivalent - use
                                     ActiveCell.Value = "#N/A"
   RAND()                            RND function

   VALUE()                           VAL function
 

NOTE: The Microsoft Excel worksheet function and the Visual Basic equivalent operator or function are not always calculated the same way and may give different results, even when they have the same name.


Using the Visual Basic equivalent operator or function is preferred for increased speed and flexibility in calculations. Additionally, the Visual Basic operator or function is available to all applications that use Microsoft Visual Basic for Applications.


Although it is recommended that you use the Visual Basic operators or functions shown in the list above, there are alternative methods for using the worksheet functions in a Visual Basic macro if necessary. As an example, you can use the ATAN worksheet in your Visual Basic macro using the ExecuteExcel4Macro or Evaluate functions:

   x = Application.ExecuteExcel4Macro("Atan(12)")
 

-or-

   x = Application.Evaluate("Atan(12)")
