I'm trying to color cells that do not start with a letter; but I'm not sure how to specify a character range in this format.

Cells contents such as:

!this one    <--- formatted
this is fine
@email.com   <--- formatted
 leading space   <--- formatted

Ideally, it would color the cell for any non-letter.





Set conditional formatting to use a custom formula. Apply the above formula.

  • The first ^ means start of the string
  • Note that the second ^ is inside of [], this means a logical NOT.
  • The a-zA-Z are a two character ranges, lowercase letters and uppercase letters.


  • 1
    I didn't realize there was a Regex function; great, I'll look into that more. Thanks again.
