1. The LOOKUP Function

The LOOKUP function searches for a value within a range or array. It offers both array and vector lookup capabilities.

Syntax:

<code>=LOOKUP(lookup_value, lookup_vector, [result_vector])</code>

Example: To find the name associated with a specific ID (assuming IDs are in column A and names in column B):

<code>=LOOKUP(A15,$A$1:$A$11,$B$1:$B$11)</code>

2. The VLOOKUP Function

VLOOKUP is Excel's most widely used lookup function. It searches for a value in the first column of a range and returns a value from the same row in a specified column.

Syntax:

<code>=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])</code>

Example: To find a customer's city using their CustomerID from the Sales table:

<code>=VLOOKUP(A15,$A$1:$C$11,3,0)</code>

3. The HLOOKUP Function

HLOOKUP functions similarly to VLOOKUP, but it searches the top row of a range and returns a value from the same column in a specified row.

Syntax:

<code>=HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])</code>

Example: Assuming the customer table is transposed horizontally (customer data in rows):

<code>=HLOOKUP(F8,$F$1:$P$4,3,0)</code>

4. The XLOOKUP Function

XLOOKUP is a more powerful and versatile function designed to supersede VLOOKUP and HLOOKUP.

Syntax:

<code>=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])</code>

Example: To find a customer's city using their ID (IDs in column A, cities in column C):

<code>=XLOOKUP(A15,$A$1:$A$11,$C$1:$C$11)</code>

5. INDEX and MATCH Functions

The combination of INDEX and MATCH offers a flexible alternative to VLOOKUP and HLOOKUP, enabling both vertical and horizontal searches.

Syntax:

<code>=INDEX(return_range, MATCH(lookup_value, lookup_range, [match_type]))</code>

Example: To find the city for a given CustomerID using INDEX and MATCH:

<code>=INDEX(C1:C11,MATCH(A15,A1:A11,0))</code>

6. The CHOOSE Function

CHOOSE returns a value from a list based on an index number.

Syntax:

<code>=CHOOSE(index_num, value1, [value2], ...)</code>

Example: To return a country name based on its number:

<code>=CHOOSE(5, "USA", "India", "Australia", "Turkey", "Britain", "France", "Sri Lanka", "Indonesia", "Mexico", "Ghana")</code>

Advantages and Drawbacks
