Establish identical Values within an index range
Hi,
I would like a formula to establish identical values within an index range.
Please see attached
Many thanks

=IF(COUNTIF($A$2:$A$15,A2)=COUNTIFS($A$2:$A$15,A2,$B$2:$B$15,B2),0,1)
To counter the Saqib's formula, here is the more elegant formula... Lol
=--(COUNTIF($A$2:$A$15,A2)<>COUNTIFS($A$2:$A$15,A2,$B$2:$B$15,B2))
And how many rows of data in there?
After copying the formula down the rows, you can copy the formula range and paste it back as values so that the formulas don't recalculate every time.
Or you can use VBA to place the formula.
In the attached, place the data from your original file in the column A and B starting from Row2 and click the button called "Place Formula" and see if it works faster than manually placing the formula.

Subodh, I have removed the absolute marks $
But that formula would fail in some scenarios. So a new formula.
=--(COUNTIF(OFFSET(A2,MAX(

Here is a formula using the indirect condition.
In fact the rows and columns are correct so a matter of inserting your new formula.
DC and DD are the F & G columns I referred to in my example.
JR being the Index column
=IF(JR14="","",IF(JR14=JR1

I think this would be even more quicker
=IF(A2=A1,G1,--(COUNTIF(A2
=IF(A2=A1,G1,--(COUNTIF(A2
Applying a bit of logic, if all values in an index range are the same they have to be the same as the Average for the index range.
Therefore, you can use:
=IF(B2=SUMIFS(B:B,A:A,A2)/
For later versions of Excel:
=IF(B2=AVERAGEIFS(B:B,A:A,
Therefore, you can use:
=IF(B2=SUMIFS(B:B,A:A,A2)/
For later versions of Excel:
=IF(B2=AVERAGEIFS(B:B,A:A,
However, if one of the values in the range is equal to the average then it will result in 0 on that line. So to allow for that:
=IF(COUNTIFS(A$1:A1,A2,C$1
One scenario where it gives the wrong result is if the first value for the Index range is equal to the average. To overcome that, I would suggest sorting the values in each range in ascending order. On the same logic, if the values are not equal to the average there has to be some that are less than the average and some that are higher. Sorting in ascending order will ensure that the first value is less than the average; if the first/lowest value is equal to the average then all of them will be.

Hi guys,
I was trying out Rob's simple solution and worked well and calculated in less than a couple of minutes, which is fast
for this 160,000 row spreadsheet
I will work with this one for now but will also run the other formulas and will claim them all as a solution if that is permissible.
Thank You Rob, Saqib and Neeraj

That can't be right. I repeated the given data for more than 160,000 rows and the formula gave the results in only a second or two.
I am leaving for home. I am going to send a file showing comparisons. You can then see the difference.
Saqib,
I have found an alternative method to arrive at the conclusion without the use of
this formula. I'm understanding more and more about this monster of a spreadsheet
Apologies for inconvenience.

Here is the file. If you see the formulas in the first few columns they take ages to compute. But if you look at the formulas in the last two columns then you would see that the calculations are very much instantaneous.

I finally got onto your formula having been away from here yesterday.
I tried your end col formula and it certainly was fast as only took a few
seconds to calculate. I'm off for a long walk and when I get back will
check out your other formula.
Thanks again Saqib your effort was certainly worthwhile from my point of view
