# Conditional Formatting Gem in #Excel: Highlight the N Closest Values to the Mean of a Range in a Filtered List by David Hager

I am extending the closest value technique I published recently to calculate the same based on a filtered list.

In this demonstration, the goal is to highlight values in a numeric range that are clostest to the average of that range in a filtered list. So, we first make the range dynamic with the following defined name formula.

NumRange =OFFSET(Sheet1!\$A\$1,1,,COUNTA(Sheet1!\$A:\$A)-1)

Then, we modify that range to include only filtered values.

fNumRange =IFERROR(IF(SUBTOTAL(3,OFFSET(NumRange,ROW(NumRange)-MIN(ROW(NumRange)),,1)),NumRange,””),””)

Next, we use that range to make an array of the absolute differences of each value of the range from the average.

ABS_Range =IFERROR(ABS(fNumRange-AVERAGE(fNumRange)),””)

We can then define a cell for the number of values to highlight.

N_Values =\$B\$2

The heavy work is done by the next formula, which creates an array of the N values to be higlighted.

Num_Array=INDEX(NumRange,N(IF(1,TRANSPOSE(MATCH(SMALL(ABS_Range,ROW(

INDIRECT(“1:”&N_Values))),ABS_Range,0)))))

This formula returns the position of each smallest deviation in the 2nd argument of the INDEX function, which then returns the values corresponding to those deviations, based on a filtered list. The use of the formula syntax needed to do this with the INDEX function is explained at the following link.

This formula can now be used in the creation of the CF, where CF Formula is =SUM(N(A1=Num_Array)), starting at A1 and applied to all of Column A.

The result of this CF is shown below. CF_Closest_Filtered

# Using the SUBTOTAL Function in #Excel To Aggregate Values From Multiple Filtered Lists by David Hager

So, imagine a scenario where 4 filtered lists reside in the same position on adjacent worksheets that have “sequential” names. Perhaps each list comes from a monthly summary, but filtering is applied differently for each list. Well, I did not build that example, but instead have 4 sheets named A to D, a list on each sheet residing in the same range and each column filled with numbers from 0 to 99. The object is to perform aggregations on the filtered data from all sheets at once (or, creating a 3D formula).

For examples on various types of “multi-worksheet” formulas, see:

https://dhexcel1.wordpress.com/2014/06/09/excel-3d-easy-as-1-2-3-and-a-b-c-and-others/

The figures below shows the results of the 2 types of 3D formulas.  The filter-enabled formula shown below sums the filtered values in the 4 filtered lists. Note that since the SUMPRODUCT function is used here, the result is NOT an array formula.

=SUMPRODUCT(SUBTOTAL(9,INDIRECT(“‘”&CHAR(ROW(\$97:\$100))&”‘!C2:C21”)))

The native Excel method for creating a 3D formula is shown here.

=SUM(A:D!C2:C21)

The result from this formula is a number much higher than the filter 3D formula since there is no way to use the native 3D referencing to construct a filtered result.

Other types of aggregation from the filtered 3D formulas, but they must be constructed as array formulas. The following formulas show the filtered MIN for the desired range and the corresponding Excel-centric 3D formula.

=MIN(SUBTOTAL(5,INDIRECT(“‘”&CHAR(ROW(\$97:\$100))&”‘!C2:C21”))) ‘array formula

=MIN(A:D!C2:C21) This example shows the formulas for the MAX 3D-filtered and Excel 3D.

=MAX(SUBTOTAL(4,INDIRECT(“‘”&CHAR(ROW(\$97:\$100))&”‘!C2:C21”)) ‘array formula

=MAX(A:D!C2:C21) There are obviously a number of variations on this theme possible. Knowing that this type of aggregation is available could possibly change the way you analyze your data. HTH!

# Using Excel 3D Formulas on Filtered Lists

By David Hager

Say, for instance, that you have 4 sheets named A-D and on each there is a list with range of A1:E21. If you filter each list and use the following formula:

=SUMPRODUCT(SUBTOTAL(9,INDIRECT(“‘”&CHAR(ROW(\$97:\$100))&”‘!C2:C21”)))

you will get the sum of each list for column C. The best part is that the sheets do not have to be contiguous.

It is important to note that a similar formula does not return a result, although you might expect it to.

=SUMPRODUCT(AGGREGATE(9,6,INDIRECT(“‘”&CHAR(ROW(\$97:\$100))&”‘!C2:C21”)))
