What is Vlook up?

Accepted Answer

Vlookup is a function in Excel that allows you to search for a value in a column and return a corresponding value from another column.

Vlookup stands for vertical lookup.
It is commonly used to find specific data in large datasets.
The function requires four arguments: lookup value, table array, column index number, and range lookup.
The lookup value is the value you want to search for.
The table array is the range of cells where the data is located.
The column index number is the column from which you want to retrieve the data.
Range lookup is an optional argument that determines whether the function should find an exact match or an approximate match.
Vlookup returns the value found in the corresponding row and column.
If an exact match is not found, it can return an error or the closest match depending on the range lookup argument.
Example: =VLOOKUP(A2, B2:D10, 3, FALSE) will search for the value in cell A2 in the range B2:D10 and return the value from the third column.
