The Excel function: ADDRESS
You can use the ADDRESS function to obtain the address of a cell in a worksheet, given specified row and column numbers. For example, ADDRESS(2,3) returns $C$2. As another example, ADDRESS(77,300) returns $KN$77. You can use other functions, such as the ROW and COLUMN functions, to provide the row and column number arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.) for the ADDRESS function.
