How to ignore text on SUM() function...

K

KLZA

Hi. I'm using the SUM() function to add cell data which contains
bandwidth or kilobyte information. The SUM cell shows the data in
kilobytes. The formula I'm using in the SUM cell is =SUM(CELL RANGE)
& " KB". My problem is that the formula ignores a cell entirely if
someone puts an alpha character after the numerics - ie 1024K instead
of 1024. Is there a way to use the SUM() function and ignore aplha
characters but not numerics? This way if someone types 1024K or 1024
it still will show as 1024K in the sum field.

try:

=SUM(IF($D$1:$D$5<>"",IF(ISNUMBER(--RIGHT($D$1:$D$5)),$D$1:$D$5,--LEFT($D$1:$D$5,LEN($D$1:$D$5)-1))))

Enter with Ctrl+Shift+Enter

Not working. I get #VALUE....

Worked ok for me, too.

You'll get #VALUE! if don't array enter**.

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

Here's another one that's a few keystrokes shorter and is normally entered.
Assumes all entries will either be a number or a number followed by the
letter K (case doesn't matter):

1024k
1024K
256
256K

=SUMPRODUCT(--(SUBSTITUTE(SUBSTITUTE(UPPER(A1:A5)&"K","KK",""),"K",".0")))

=SUMPRODUCT(--(LEFT(A1:A4,FIND("K",UPPER(A1:A4)&"K")-1)&".0"))

Another one that is still a few keystrokes shorter. Pretty sure I got this
idea from one of your previous posts <g>

For the OP, you might also consider using data validation to help prevent
folks from entering text. Click Data/Validation and use whole number or
decimal. This formula will only work for entries with a "K" included.

not sure about the eg data where kb(s) are generated on same format?...

maybe a more versatile formula which will read/release any alpha(s)..can be
interesting?...

Yep, nice one!

I had a feeling it could be reduced even further.

You came up with the *best* solution:

I think if there are any more conditions/variables then the OP should take
JMB's advice:

and further still
....

=SUMPRODUCT(--(LEFT(A1:A4,SEARCH("K",A1:A4&"K")-1)&".0"))

Probably could be done w/a helper column, but I don't see how to get it all
in one formula w/o ending up w/an array of arrays (for lack of a better
description). But, just because I don't see it doesn't mean it can't be
done.

I would probably resort to a macro before putting the time into finding a
single formula solution (or smack the person who put the alpha data in and
make them redo it).

Sub Test()
Dim lngCount As Long

For lngCount = 65 To 90
Selection.Replace _
what:=Chr(lngCount), _
replacement:="", _
lookat:=xlPart, _
searchorder:=xlByRows, _
matchbyte:=False
Next lngCount
End Sub

Ugly, but define the name seq referring to

=ROW(INDEX(Sheet1!$1:$65536,1,1):INDEX(Sheet1!$1:$65536,64,1))

and use array formulas like

=SUM(--LEFT(colrange,MMULT(--ISNUMBER(-(MID(colrange,1,
TRANSPOSE(seq))&"0")),seq^0)))

Better to download and install Laurent Longre's MOREFUNC.XLL add-in and use

=SUM(--REGEX.MID(A1:A8,"^[-+]?((\d+(\.\d*)?)|((\d*\.)?\d+))"
&"([Ee][-+]?([1-2]?\d{1,2}|30[0-7]))?"))

which should parse any substring Excel would consider numeric with decimal
fractional part and/or scientific notation. Handling fractions, dates and
times would be a bit trickier.

seq = 1:64. Why 64? Seems like an arbitrary number smaller than the
"standard" arbitrary 255 because you don't expect a string longer than 64
characters.

Ugly, so you say, but still more efficient than anything I can come up with.
Thanks for posting a formula solution - I had tried something w/MMULT, but
couldn't get it to go and was curious to if you would come up w/something.

And, yes I agree the macro approach is quite limited.

The STRING may be longer than 64 chars, but the numeric substring at
the beginning would have to be no more than 64 chars. Numeric strings
of more than 64 chars aren't going to produce meaningful sums anyway.
