Use Excel built-in functions to find data in a table or a range of cells

Summary

This step-by-step article describes how to find data in a table (or range of cells) by using various built-in functions in Microsoft Excel. You can use different formulas to get the same result.

Create the Sample Worksheet

This article uses a sample worksheet to illustrate Excel built-in functions. Consider the example of referencing a name from column A and returning the age of that person from column C. To create this worksheet, enter the following data into a blank Excel worksheet.

You will type the value that you want to find into cell E2. You can type the formula in any blank cell in the same worksheet.

A

B

C

D

E

1

Name

Dept

Age

2

Henry

501

28

Mary

Stan

201

Term Definitions

This article uses the following terms to describe the Excel built-in functions:

Term

Definition

Example

Table Array

The whole lookup table

A2:C5

Lookup_Value

The value to be found in the first column of Table_Array.

E2

Lookup_Array
-or-
Lookup_Vector

The range of cells that contains possible lookup values.

A2:A5

Col_Index_Num

The column number in Table_Array the matching value should be returned for.

3 (third column in Table_Array)

Result_Array
-or-
Result_Vector

A range that contains only one row or column. It must be the same size as Lookup_Array or Lookup_Vector.

C2:C5

Range_Lookup

A logical value (TRUE or FALSE). If TRUE or omitted, an approximate match is returned. If FALSE, it will look for an exact match.

FALSE

Top_cell

This is the reference from which you want to base the offset. Top_Cell must refer to a cell or range of adjacent cells. Otherwise, OFFSET returns the #VALUE! error value.

Offset_Col

This is the number of columns, to the left or right, that you want the upper-left cell of the result to refer to. For example, "5" as the Offset_Col argument specifies that the upper-left cell in the reference is five columns to the right of reference. Offset_Col can be positive (which means to the right of the starting reference) or negative (which means to the left of the starting reference).

Functions

LOOKUP()

The LOOKUP function finds a value in a single row or column and matches it with a value in the same position in a different row or column.

The following is an example of LOOKUP formula syntax:

   =LOOKUP(Lookup_Value,Lookup_Vector,Result_Vector)


The following formula finds Mary's age in the sample worksheet:

   =LOOKUP(E2,A2:A5,C2:C5)

The formula uses the value "Mary" in cell E2 and finds "Mary" in the lookup vector (column A). The formula then matches the value in the same row in the result vector (column C). Because "Mary" is in row 4, LOOKUP returns the value from row 4 in column C (22).

NOTE: The LOOKUP function requires that the table be sorted.

VLOOKUP()

The VLOOKUP or Vertical Lookup function is used when data is listed in columns. This function searches for a value in the left-most column and matches it with data in a specified column in the same row. You can use VLOOKUP to find data in a sorted or unsorted table. The following example uses a table with unsorted data.

The following is an example of VLOOKUP formula syntax:

    =VLOOKUP(Lookup_Value,Table_Array,Col_Index_Num,Range_Lookup)

The following formula finds Mary's age in the sample worksheet:

   =VLOOKUP(E2,A2:C5,3,FALSE)

The formula uses the value "Mary" in cell E2 and finds "Mary" in the left-most column (column A). The formula then matches the value in the same row in Column_Index. This example uses "3" as the Column_Index (column C). Because "Mary" is in row 4, VLOOKUP returns the value from row 4 in column C (22).

INDEX() and MATCH()

You can use the INDEX and MATCH functions together to get the same results as using LOOKUP or VLOOKUP.

The following is an example of the syntax that combines INDEX and MATCH to produce the same results as LOOKUP and VLOOKUP in the previous examples:

    =INDEX(Table_Array,MATCH(Lookup_Value,Lookup_Array,0),Col_Index_Num)

The following formula finds Mary's age in the sample worksheet:


    =INDEX(A2:C5,MATCH(E2,A2:A5,0),3)

The formula uses the value "Mary" in cell E2 and finds "Mary" in column A. It then matches the value in the same row in column C. Because "Mary" is in row 4, the formula returns the value from row 4 in column C (22).

NOTE: If none of the cells in Lookup_Array match Lookup_Value ("Mary"), this formula will return #N/A.

OFFSET() and MATCH()

You can use the OFFSET and MATCH functions together to produce the same results as the functions in the previous example.

The following is an example of syntax that combines OFFSET and MATCH to produce the same results as LOOKUP and VLOOKUP:

   =OFFSET(top_cell,MATCH(Lookup_Value,Lookup_Array,0),Offset_Col)

This formula finds Mary's age in the sample worksheet:

   =OFFSET(A1,MATCH(E2,A2:A5,0),2)

The formula uses the value "Mary" in cell E2 and finds "Mary" in column A. The formula then matches the value in the same row but two columns to the right (column C). Because "Mary" is in column A, the formula returns the value in row 4 in column C (22).
