In the same way as you coded it: with a reverse table

So for table
A or B Jan
B or C Feb
D or E Mar

Just make another that says
Jan A or B
Feb C or D
Mar E or F

If you want it to say which between A and B, you will have to tell us and
Excel what the difference between A and B is.

i have a month code table.

A or B denote January
C or D denote Febuary and so on until Dec.

How can I decode a list?
