Assuming that
-- You have list of abbreviations on Sheet2!A2:A10
-- You are entering values on sheet1 and from cell T2
than try this.....
--Create a helper column on sheet1 (say on col. AA from cell AA2), which you may hide.
on cell AA2 use the below formula and copy it down
Now select the T2:"as far as needed" and make a new rule for conditional formatting using the following formula......![]()
AA2 =IF(T2<>"",NOT(ISNUMBER(MATCH(T2,Sheet2!$A$2:$A$10,0))))
and set the format as per your requirement.![]()
=AA2=TRUE
For detail, pls find the attached sheet.
Hope that helps.
