Counting the (1) in a binary code string !

[serge]

Hi,

I'm working with binary code on the left side from P:AN, and on the right, I'm looking for a formula that will be able to count the (1) as long as they are not separated by a (0).So for example the first row P9:AN9.The formula will start in cell AQ9 and drag to the right, is that possible ? Thank you.

Somebody asked a similar question just 2 or 3 days ago but for one column.
That was resolved and should be easily applied to rows.
I think the person was asking to COUNT consecutive 1's.
That may be enough for both of us to do a search of recent days or maybe wait for the "solver" to appear.


(Hope for the "solver" unless you are successful, I tried a few options but sadly missed.)

Does any one has a idea please ?

I know you asked for a formula, but I could not think of one, so I developed a macro for you to consider instead...

[table="width: 500"]
[tr]
	[td]Sub CountConsecutiveOnes()
  Dim R As Long, X As Long, Ones As Variant, Data As Variant, Result As Variant
  Data = Range("AN9").CurrentRegion.Value
  ReDim Result(1 To UBound(Data, 1), 1 To UBound(Data, 2))
  For R = 1 To UBound(Data)
    Ones = Split(Application.Trim(Replace(Join(Application.Index(Data, R), ""), 0, " ")))
    For X = 0 To UBound(Ones)
      Result(R, X + 1) = Len(Ones(X))
    Next
  Next
  Range("AQ9").Resize(UBound(Result, 1), UBound(Result, 2)) = Result
End Sub[/td]
[/tr]
[/table]

HOW TO INSTALL MACROs
------------------------------------
If you are new to macros, they are easy to install and use. To install it, simply press ALT+F11 to go into the VB editor and, once there, click Insert/Module on its menu bar, then copy/paste the above code into the code window that just opened up. That's it.... you are done. To use the macro, go back to the worksheet with your data on it and press ALT+F8, select the macro name (CountConsecutiveOnes) from the list that appears and click the Run button. The macro will execute and perform the action(s) you asked for. If you will need to do this again in this same workbook, and if you are using XL2007 or above, make sure you save your file as an "Excel Macro-Enabled Workbook (*.xlsm) and answer the "do you want to enable macros" question as "Yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.

Maybe this array formula

AQ9 copied across and down
=IFERROR(INDEX(FREQUENCY(IF($P9:$AN9=1,COLUMN($P9:$AN9)),IF(($P9:$AN9=0)*($Q9:$AO9=1),COLUMN($P9:$AN9))),COLUMNS($AQ9:AQ9)+1),"")
Ctrl+Shift+Enter

[Marcelo Branco]

oops...my formula fails in some situations rethinking...

[Marcelo Branco]

Small adjustment...

New version
Array formula in AQ9 copied across and down
=IFERROR(INDEX(FREQUENCY(IF($P9:$AN9=1,COLUMN($P9:$AN9)),IF(($P9:$AN9=0)*($Q9:$AO9=1),COLUMN($P9:$AN9))),COLUMNS($AQ9:AQ9)+IF($P9=1,0,1)),"")
Ctrl+Shift+Enter
