Hello,
set up a table in your workbook that lists the codes and the text side by side in two separate columns
In another area of the spreadsheet, for example in D1 enter the number. In E1 enter this Vlookup formula
=Vlookup(D1,$A$1:$B$3,2,false)
E1 will now contain the text. Copy E1 down and enter more codes in column D.
You can then perform a count of codes in column D to find out how often each code has been used.
This approach can be refined with error trapping to avoid N/A errors in column E if the cell in column D is empty.
cheers,
