Formula IF or Switch with multiple values

[Slim_BENAZIZA]

Hello,

I have a table with fields like this :

The "First char" field is a formula that return the first character UPPER of the "First name" field.

Then, the field "check" is used to filter a view from A to E. So i need a formula that show "OK" if the "First char" field contain A or B or C,,,,,,,,,E or else it will show "KO"

Any ideas how to do it ?

Thanks.

Hi @Slim_BENAZIZA 

try this formula: 

IF(ISERROR(REGEX_EXTRACT({First char},"[A B C D E]"))=1, "KO", "OK")

I hope this helps!
