Traditionally, the spread sheet of the Excel is set by columns and rows. Columns in Microsoft Excel 2016 are denoted by capital Alphabets, starting with ‘A’ and ending with ‘XFD’. On the other hand, rows in Microsoft Excel 2016 are counted in numeric, commencing with ‘1’ and ending on ‘1,048,576’ So, technically, you may pinpoint the location of any cell on the spread sheet in ‘ColumnRow’ where columns are identified by alphabet and the row is identified by numeric. For example, the location of any cell in spread sheet is pinpointed by ‘G9’ when it is in column ‘G’ and row ‘9’.
Alternatively, you may identify location of any cell in ‘R1C1’ style, i.e. row ‘1’ and column ‘1’, making it easier to search the cell location. 
For example, if the cell is in rows 9 while the cell is in column 7, RICI style would display ‘R9C7’. For some users, this may look easier to understand.
You may also convert the reference style into spread sheet to RICI style but if you need any help, just see the instructions.
