    ISNUMBER not working correctly

    I'm using the following formula to determine if the 3rd character from the right is a number and return a true/false accordingly

    =ISNUMBER(LEFT(RIGHT(A1,3),1))

    Thing is it's not working as intended, it always return a false even if the character is a number

    What gives?

    once you use LEFT it changes it to TEXT

    maybe this

    Re: ISNUMBER not working correctly

    Not sure why you're using the left function as well but this should do the job:

    =ISNUMBER(VALUE(LEFT(RIGHT(A1,3),1)))

    Re: ISNUMBER not working correctly

    You can alsousethings like:

    =ISNUMBER(--LEFT(RIGHT(A1,3),1))

    and

    =ISNUMBER(LEFT(RIGHT(A1,3),1)+0)

    to convert the text values returned by LEFT and RIGHT back into numbers.
