This page shows how to use the Excel Vlookup Function when the [range_lookup] argument is set to TRUE (or is omitted).
When the [range_lookup] is set to TRUE, this tells the Vlookup function that, if an exact match to the lookup_value is not found, then the closest match below the lookup_value should be returned instead.
It is important to remember that, when using this option, the left-hand column of the table_array must be in ascending order. If it isn't, the results from the Vlookup function may be unpredictable.
|$0 - $999.99||1%|
|$1,000 - $4,999.99||3%|
|$5,000 - $19,999.99||4%|
Imagine a bank account has a variable interest rate that depends upon its balance, as shown in the table on the rightabove table. These interest rate categories are stored in the "Interest Rate" spreadsheet below.
Bank Accounts spreadsheet with Vlookup functions:
For each of the bank accounts in the above spreadsheet, the Vlookup function finds the closest value below the current balance, in column A of the "Interest Rates" spreadsheet. The function then returns the corresponding value from column C of this spreadsheet.

The first call to the Vlookup function, in cell C2 is:
The table below explains the arguments that are supplied to this function:
|B2||-||lookup_value is therefore the value 5.69.The|
|'Interest Rates'!A2:C5||-||lookup_value 5.69.The Vlookup function will search down the left column (i.e. column A) of this array, when searching for the closest match equal to or below the|
|3||-||The col_index_num argument is set to the value 3, meaning that the value to be returned by the Vlookup function should be taken from column 3 of the supplied table_array (i.e. from column C of the "Interest Rates" spreadsheet).|
|TRUE||-||Note that this value could have been omitted from the above formula as, by default, it uses the value TRUE.|
