Counting Consecutive Cells with value

[JulieO]

I use Excel 2007 and I'm trying to find code or a formula that would count the number of consecutive cells in a row from left to right until it there is 0, Below is an example of what I'm trying to do:

<TABLE style="WIDTH: 245pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=324><COLGROUP><COL style="WIDTH: 28pt" span=5 width=37><COL style="WIDTH: 22pt; mso-width-source: userset;

It worked! Thanks

It worked! Thanks

No problem. Thanks for the feedback!

MrKnowz,
Why the 9.99E+307 in the match? Why not just 1?

 

[MrKowz]

MrKnowz,
Why the 9.99E+307 in the match? Why not just 1?

Due to needing to find the location of the last 0, I had to use a little trick involving lookup-style formulas.

9.99E+307 is often referred to as BigNum (the biggest number Excel can handle). It is used in lookup formulas to always refer to the last numerical value.

If you look closely at the MATCH function I used, you'll notice that I did not give it the third argument of 0 (or FALSE), which indicates an exact match:

MATCH(9.99E+307,IF(A2:H2=0,1,""))

So this function is going to look for the closest match in the array defined by A2:H2=0. If I would have simply had it search for 0 with an exact match, it would return the first occurance. Same goes for if I had put a 1 in the above statement instead of 9.99E+307, it would have found its closest match on the first occurance, thereby not even looking at the second.

Lets look at the data provided by the OP:

By using the conditional array in the MATCH function (and confirming entry with CTRL+SHIFT+ENTER to evaluate as an array formula), the MATCH doesn't look at the data that we see. It actually sees a different set of data; When a cell value is 0, it see 1. When a cell value is not 0, it sees a blank:

So to find the location of the last "1" that it sees, we can't simply search for 1. We have to use a number larger than any value that could be found in the array. By doing this, it will always return the location of the last numeric value. If I would have instead built the formula like this:

MATCH(9.99E+307,IF(A2:H2=0,1,0))

That would create a behind-the-scenes table that looks like this:

Since we now have numeric data in every cell, the MATCH would return column H every time.

We can similarly use this "BigNum" trick to find the last populated cell with text, but instead of using 9.99E+307, we use Rept("z",255), basically a string that would always be last alphabetically.

Hope that clears it up a bit!

That is so good MrKowz.

Hi Please can you help me with something very similar? I would like to count the maximum number of consecutive cells containing the number "1". My data only has "1"s or blank cells.

 

[viper_iggi]

Sorry - here is the table!

Excel 2007
	A	B	C	D	E	F	G	H	I	J
1	A1	B1	C1	D1	E1	F1	G1	H1	I1	Result
2	1	1	1	1		1		1	1	4
3	1	1	1		1	1	1		1	3
4	1									1
5								1	1	2
Sheet4

J2, control+shift+enter, not just enter, and copy down:

=MAX(FREQUENCY(IF(A2:I2=1,COLUMN(A2:I2)),IF(A2:I2<>1,COLUMN(A2:I2))))
