Number of upper case letters in a string

[Ceeyee]

If I need to find the number of upper cased letters in a string, do I have to use a loop or there is quicker ways?

Thanks.

Hey, how do you know to write POLUIÇÂO?

Nice string to this thread

What makes you think looping is slow? The following function makes use of some of VB's fastest String functions (I would not be surprised to find this code to be faster than the non-looping code solutions already posted)...

Function CountUppers(S As String) As Long
  Dim X As Long
  Const Uppers As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
  For X = 1 To Len(S)
    CountUppers = CountUppers - (InStr(Uppers, Mid(S, X, 1)) > 0)
  Next
End Function

Careful, PGC01
=SUMPRODUCT(0+EXACT(MID(A2,ROW(INDIRECT("1:"&LEN(A2))),1),UPPER(MID(A2,ROW(INDIRECT("1:"&LEN(A2))),1))))
gets tripped up by spaces and any non-letter characters:

Example:
For this string: a,b!,@ d#e&,;Z

The formula returns: 10

Hi Ron

Ooops, thank you.

You are, of course, right. I was thinking that the formulae were just aiming at English words, and forgot that the solution should work for a whole string.

This is first correction that comes to mind:

=SUMPRODUCT(0+EXACT(MID(A3,ROW(INDIRECT("1:"&LEN(A3))),1),UPPER(MID(A3,ROW(INDIRECT("1:"&LEN(A3))),1)))*(EXACT(LOWER(MID(A3,ROW(INDIRECT("1:"&LEN(A3))),1)),UPPER(MID(A3,ROW(INDIRECT("1:"&LEN(A3))),1)))=FALSE))

I'll check this thread tomorrow, but now, to bed.

Function CountUppers(S As String) As Long
  Dim X As Long
  Const Uppers As String = "[COLOR=darkred][COLOR=black]ABCDEFGHIJKLMNOPQRSTUVWXYZ[/COLOR]ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ[/COLOR]"
  For X = 1 To Len(S)
    CountUppers = CountUppers - (InStr(Uppers, Mid(S, X, 1)) > 0)
  Next
End Function

To expand on my previous message... in light of the comments about accented letters, the function I posted can be made to work with them as well... simply add whatever accented upper case letters you want to the letter string being assigned to the constant named Uppers (in the Const statement) and they will be counted as well. Not being well versed in foreign languages, I have no idea if I added the correct accented letters (shown in red) in my code above or not, but you should get the idea from how it is constructed.

(I would not be surprised to find this code to be faster than the non-looping code solutions already posted)...

Still up.

Rick, I agree completely. I'm a big fan of regular expressions, it's a fantastic text parsing tool, but heavy. For a simple case like this one a loop will be much more efficient.



An alternative for a udf that accepts letters with diacritics (a translation of my last formula):

Function CountUppers(s As String) As Long
  Dim j As Long, c As String
  
  For j = 1 To Len(s)
      c = Mid(s, j, 1)
      If (UCase(c) <> LCase(c)) And (c = UCase(c)) Then CountUppers = CountUppers + 1
  Next
End Function

Remark: I assume that the module does not have in its header the option compare text.
