Excel if multiple conditions

[Hellomimi]

Hello, I want to know if I have master contact list, and there is a row indicated member’s country of birth, if I will like to change the answer into the following codes in the list, say USA=1, CHINA=2, INDIA=3, UK=4, GERMAN=5, ITALY=6… should I use If formula? Thank you so much.

The best solution may depend on the number of countries to be considered in the workbook. If you only have 6, you could use SWITCH:

=SWITCH(A1,"USA",1,"CHINA",2,"INDIA",3,"UK",4,"GERMANY",5,"ITALY",6,"no such")

If the list is much longer you might consider creating a dedicated lookup table in the sheet and then use XLOOKUP.
