Exact Match in VLOOKUP

Question 33: Exact Match in VLOOKUP

Set the `range_lookup` argument to `FALSE` for an exact match in `VLOOKUP`.

VLOOKUP Function

Question 31: VLOOKUP Function in Excel

VLOOKUP (vertical lookup) is an Excel function used to search for a specific value in the first column of a table and return a corresponding value in the same row from a designated column. It is a powerful tool for looking up information within a dataset. The function is designed to find both exact and approximate matches.

Question 32: How VLOOKUP Works

VLOOKUP searches for a lookup value in the first column of a specified range. When it finds a match (or the closest match, depending on the `range_lookup` parameter), it returns a value from the same row in a column you specify.

Syntax:

VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

• lookup_value: The value to search for.
• table_array: The range containing the data.
• col_index_num: The column number in `table_array` containing the desired return value.
• range_lookup: TRUE (approximate match); FALSE (exact match).

Question 33: Exact Match in VLOOKUP

To perform an exact match using VLOOKUP, set the `range_lookup` argument to `FALSE`. This ensures that VLOOKUP only returns a result if it finds an exact match for the `lookup_value` in the first column of the table array.

=VLOOKUP(104, A1:D8, 3, FALSE)  //Finds the value in column 3 of the range A1:D8 that matches 104 in column A

(Example data would be needed in cells A1:D8 to demonstrate the output. The output would be the value found in the third column of the row containing 104 in the first column.)
