When to use VLOOKUP
The VLOOKUP function is useful when you need to find an information by row, within the same sheet or within another one, in a specific array of columns.

How to use VLOOKUP in Excel
The VLOOKUP formula in Excel includes 3 required arguments and 1 optional (range_lookup).
The VLOOKUP formula is =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
• lookup_value – the value you want to look up.
It can be a specific value (“January”) or a reference to a cell (B2). Note that the value must be in the 1st column of the range of cells selected as table_array.
• table_array – the range of cells in which the lookup_value and the return value you want to find are.
• col_index – the column number where the return value is, within your table_array.
The 1st column within your table_array is number 1.
• range_lookup – logical value specifying if you want the VLOOKUP function to find an exact match (0/FALSE) or an approximate one (1/TRUE).
If you don’t specify this argument, the default value is always 1/TRUE.
Tips when using VLOOKUP
– Make sure the return value is on the right side of the column you search from.
– We recommend using 0 as the range_lookup argument, to avoid unwanted results.
– You can use wildcard characters in the lookup_value argument if range_lookup is 0/FALSE and lookup_value is text. A question mark (?) will search for any single character and an asterisk (*) will match any sequence of characters.
– Return value will be 0 in Excel if the cell containing the return value is empty. If the cell containing the value you need is a formula, the return value will be the result of the formula.
VLOOKUP examples in Excel
Searching a value within the same worksheet – reference
In this example, we want to find the season (value to return) associated to the month mentioned as lookup_value; lookup_value is a reference (D2, D3, etc.).
Searching a value within the same worksheet – specific value
In this example, we want to find the season (value to return) associated to the month of August; lookup_value is a specific value (“August”).
Searching a value within the same worksheet – wildcard
In this example, we want to know the age of Jean-Paul but we don’t want to write his name entirely to save time; lookup_value is a specific value. We are using the wildcard *.
Using VLOOKUP between two sheets
In this example, we want to find the season (value to return) associated to the month mentioned as lookup_value; lookup_value is a reference. The data is on the sheet “data”.
The Excel sheet with the data we need:
The Excel worksheet with our VLOOKUP formula:
The VLOOKUP formula we used, explained: =VLOOKUP(A2,data!C:D,2,0).
A2 – the reference of lookup_value.
data!C:D – the value to return is in the sheet named data and the columns we need are columns C and D. In column C, we have the lookup_value and in column D the value to return.
Again, the value must be in the 1st column of the range of cells selected as table_array so we could not select data!A:D as table_array in this example.
2 – the value to return is in column number 2.
0 – we want an exact match.
