A slightly different cell address

The address of a cell in Excel is formed by combining the column label and the row number. For example, the address A1 indicates that it is a cell that is in the first row of column A. However, we can also assign an address in another way- by using the row number label and the column number. Thus, cell A1, in this alternative notation, would have the address R1C1. How to change the way the address is assigned and can it be of practical use?

Absolute and relative cell address

Each cell in the table has an address that consists of the name of the row and column in the cross section of which it is located. However, sometimes it is necessary to indicate both a worksheet or a workbook (document), it belongs so that we could use it as an operand in some form. Below it will be the address of the cell address that uniquely determines where it is located.
