Conditional formatting with AND, OR

[Lucky]

Hi All,
I need to add conditional formatting on a cell.
A requirement is: if the cell should be highlighted yellow if value contains letters A, F, or T.

I’m trying to use “Format only cells that contain” -> Cell value -> Equal to -> AND (“A”, “F”, “T”), but looks the excel takes it literally ="AND(""A"", ""B"", ""C"")"

What would you recommend?

Hi,

Here's one way.

In the name manager (on the formulas tab), define a name called Letters which refers to this:
={"A","F","T"}

Then, in the conditional formatting, create a new rule which uses a formula to determine which cells to format as this:
=OR(ISNUMBER(FIND(Letters,A1)))

Where A1 is the subject cell.


This will be case sensitive. If you don't want it to be case sensitive then use the SEARCH() function instead of FIND().

Thanks Colin,
It works


I'm going to use this rule for a range of cell $A$2:$E$10, where $A$1:$E$3 is a header row.
I assigned the formula =OR(ISNUMBER(FIND(Letters,A1))) to the range - and it's working. I don't understand that. FIND(find text1, within text2) - the function returns position number of text2 in text1. My A1 contains some text without T, F, A, and when I enter a, f, or t in $A$2:$E$10 I'm getting formated text.
