In this example we are going to use two lists with identical columns in excel 2007. It is easy to modify the countifs function if your columns are not ordered.

This is the first example list on sheet: List 1

Sheet: List 2

### Create named ranges

There is really no need for named ranges in this example, although they shorten array formulas considerably.

1. Select A2:A13 on sheet "List 2"
2. Type Year in Name Box
3. Press Enter

Repeat with remaining ranges:
Sheet: List 2 , Range:B2:B13, Name: Asset
Sheet: List 2 , Range:C2:C13, Name: Cost
Sheet: List 1 , Range:A2:A11, Name: Year1
Sheet: List 1 , Range:B2:B11, Name: Asset1
Sheet: List 1 , Range:C2:C11, Name: Cost1

### Filter records existing in only one list, excel 2007

Array formula in cell A4:

=INDEX('List 1'!\$A\$2:\$C\$11, SMALL(IF(COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)=0, ROW(Year1)-MIN(ROW(Year1))+1), ROW(A1)), COLUMN(A1)) + CTRL + SHIFT + ENTER

Copy cell A4 and paste it to the right as far as needed. Copy cells and paste down as far as needed.

Array formula in cell A14:

=INDEX('List 2'!\$A\$2:\$C\$13, SMALL(IF(COUNTIFS(Year1,  Year,  Asset1,  Asset,  Cost1,  Cost)=0, ROW(Year)-MIN(ROW(Year))+1), ROW(A1)), COLUMN(A1)) + CTRL + SHIFT + ENTER

Copy cell A4 and paste it to the right as far as needed. Copy cells and paste down as far as needed.

### Explaining the array formula in cell A4

Step 1 - Find records existing only in List 1

Let us take a look at the bolded part of the formula.

=INDEX('List 1'!\$A\$2:\$C\$11, SMALL(IF(COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)=0, ROW(Year1)-MIN(ROW(Year1))+1), ROW(A1)), COLUMN(A1))

COUNTIFS(criteria_range1,criteria1, criteria_range2, criteria2...)
Counts the number of cells specified by a given set of conditions or criteria

COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)

becomes

COUNTIFS({1997, 1998, 1998, 1999, 2001, 2002, 2002, 2002, 2002, 2003, 2003, 2004},{1997, 1998, 1998, 1999, 2001, 2002, 2002, 2002, 1996, 2002}, {Printer, Press, Copier, Copier, Printer, Copier, Printer, Computer, Lift, Vacuum, Press, Copier},{Printer, Press, Copier, Copier, Printer, Copier, Printer, Computer, Computer, Copier},{2025, 11000, 1575, 1199, 825, 1231, 1788, 17090, 15464, 359, 6900, 799},{2025, 11000, 1575, 1299, 825, 1231, 1788, 17090, 15275, 1577})

and returns this array: {1, 1, 1, 0, 1, 1, 1, 1, 0, 0}

COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)=0

becomes

{1, 1, 1, 0, 1, 1, 1, 1, 0, 0}=0

and returns

{FALSE, FALSE, FALSE, TRUE, FALSE, FALSE, FALSE, FALSE, TRUE, TRUE}

Step 2 - Convert boolean array to row numbers

IF(COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)=0, ROW(Year1)-MIN(ROW(Year1))+1)

becomes

IF({FALSE, FALSE, FALSE, TRUE, FALSE, FALSE, FALSE, FALSE, TRUE, TRUE}, ROW(Year1)-MIN(ROW(Year1))+1)

becomes

IF({FALSE, FALSE, FALSE, TRUE, FALSE, FALSE, FALSE, FALSE, TRUE, TRUE}, {1, 2, 3, 4, 5, 6, 7, 8, 9, 10})

and returns

{FALSE, FALSE, FALSE, 4, FALSE, FALSE, FALSE, FALSE, 9, 10}

Step 3 - Return the k-th smallest value

SMALL(IF(COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)=0, ROW(Year1)-MIN(ROW(Year1))+1), ROW(A1))

becomes

SMALL({FALSE, FALSE, FALSE, 4, FALSE, FALSE, FALSE, FALSE, 9, 10}, ROW(A1))

becomes

SMALL({FALSE, FALSE, FALSE, 4, FALSE, FALSE, FALSE, FALSE, 9, 10}, 1)

and returns 4.

Step 4 - Return a value of the cell at the intersection of a particular row and column

=INDEX('List 1'!\$A\$2:\$C\$11, SMALL(IF(COUNTIFS(Year,  Year1,  Asset,  Asset1,  Cost,  Cost1)=0, ROW(Year1)-MIN(ROW(Year1))+1), ROW(A1)), COLUMN(A1))

becomes

=INDEX('List 1'!\$A\$2:\$C\$11, 4, COLUMN(A1))

becomes

=INDEX('List 1'!\$A\$2:\$C\$11, 4, 1)

and returns 1999.
