Dear experts

Need a formulae which will identify the presence of a dot (.) in a text string and if the condition is met, the formulae will return true.

Example (cell A2)

Xyz.xls      Formulae should return ‘True’

The idea is that if the result of the find/search formulae is true, then i would like to put “”, no character, else put the valuein the cell A2.

Kindly provide the formulae for the same.

Thank you

Try this

Where A1 has the text

=IFERROR(IF(FIND(".",A1,1),"True","False"),"False")

I guess you want A1 rather than F1.

Shortened it to

=IFERROR(IF(FIND(".",A1,1),"True"),"False")

What you probably want to do is use the following:
=NOT(ISERROR(FIND(".",A2)))

You could also use COUNTIF

=IF(COUNTIF(A1,"*.*"),"",A1)

If you just want True/False, then:
=ISNUMBER(FIND(".",A2))

Barry/Rory, kindly advise IYO

is?
=IF(ISNUMBER(FIND(".",F1)),F1,"")

better than?
=IF(ISERROR(FIND(".",F1)),"",F1)

clearly I have slightly modified my formula @34863823 and I agree that Stephen's response is more complete given the later part of the question, I just wondered if ISNUMBER is better/more efficient than ISERROR?

I doubt if there's much in it really, Runrigger. I think I have a slight preference for ISNUMBER because it's a positive test......but that's probably just me.

Otherwise which one you use might depend on how you need to structure any other parts of the formula. In this case, in a simple IF function, obviously you can just swap the TRUE/FALSE arguments as per your example so it probably doesn't matter....

Thanks for the feed back Barry, I didn't think there would be much in it, but a positive test I guess is the better approach!
