## Highlight closest number

This post demonstrates how to highlight records with the closest value to a criterion, you can also choose to highlight the second closest value (or more).

You can also extract the number using the formula described in this article:Â Find closest value,Â perhaps you are also interested in how to find theÂ numbers in a total closest to a given sum.

### Conditional formatting formula

This formula won't work in Excel 2010 and later Excel versions, simply create a named range containing the formula above. Then use that name as the conditional formatting formula, get the file later in this article if you need to see exactly how I did it.

### How to apply conditional formatting formula

Make sure you adjust cell references to your excel sheet.

- Select cells B6:D10
- Press with left mouse button on "Home" tab
- Press with left mouse button on "Conditional Formatting" button
- Press with left mouse button on "New Rule.."
- Press with left mouse button on "Use a formula to determine which cells to format"
- Type
*=OR(ABS($C6-$C$2)=SMALL(ABS($C$6:$C$10-$C$2), ROW($A$1:INDEX($A:$A, $C$3))))*in "Format values where this formula is TRUE" window.

(*The formula displayed in the image above is not used in this article*) - Press with left mouse button on "Format.." button
- Press with left mouse button on "Fill" tab
- Select a color for highlighting cells.
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"
- Press with left mouse button on "Ok"

### How the conditional formatting formula works in cell C6

=OR(ABS($C6-$C$2)=SMALL(ABS($C$6:$C$10-$C$2), ROW($A$1:INDEX($A:$A, $C$3))))

*Step 1 - Calculate age differences*

=OR(ABS($C6-$C$2)=SMALL(**ABS($C$6:$C$10-$C$2), **ROW($A$1:INDEX($A:$A, $C$3))))

ABS(number) returns the absolute value of a number, a number without its sign.

ABS($C$6:$C$10-$C$2)

becomes

ABS({25;46;33;26;47}-30)

becomes

ABS({-5;16;3;-4;17})

and returns {5;16;3;4;17}

**Step 2 - Create an array with the same size as chosen records to highlight in cell C3.**

=OR(ABS($C6-$C$2)=SMALL(ABS($C$6:$C$10-$C$2),**ROW($A$1:INDEX($A:$A,$C$3)))**)

ROW($A$1:INDEX($A:$A,$C$3)))

becomes

ROW($A$1:INDEX($A:$A,2)))

becomes

ROW($A$1:$A$2)

and returns {1;2}

*Step 3 - Return the two smallest numbers in array*

=OR(ABS($C6-$C$2)=**SMALL(ABS($C$6:$C$10-$C$2),ROW($A$1:INDEX($A:$A,$C$3)))**)

SMALL(array,k) returns the k-th smallest number in this data set.

SMALL(ABS($C$6:$C$10-$C$2),ROW($A$1:INDEX($A:$A,$C$3)))

becomes

SMALL({5;16;3;4;17};{1;2})

and returns {3;4}

*Step 4 - Is cell value in C6 equal to any number in array?*

=OR(ABS($C6-$C$2)=SMALL(ABS($C$6:$C$10-$C$2),ROW($A$1:INDEX($A:$A,$C$3))))

becomes

OR(logical1, logical2, ...) checks whether any of the arguments are TRUE, and returns TRUE or FALSE. Returns FALSE if only all arguments are FALSE.

$C6 is a relative AND absolute cell reference.

=OR(ABS($C6-$C$2)={3;4})

becomes

=OR(ABS(25-30)={3;4})

becomes

=OR(ABS(-5)={3;4})

becomes

=OR(5={3;4})

becomes

=OR({5=3,5=4})

becomes

=OR({FALSE,FALSE})

and returns FALSE. Row 6 is not highlighted.
