  • Picture and text skills
  • Case

Returns the value in a vector or array. The LOOKUP function has two syntax forms: vector and array.

Tip: The values ​​of LOOKUP_vector must be sorted in ascending order: ..., -2, -1, 0, 1, 2, ..., A-Z, FALSE, TRUE;

Otherwise, the function LOOKUP cannot return the correct result. The text is not case sensitive.


1. Vector form

A vector is a range containing only one row or column.

The vector form of the LOOKUP function searches for values ​​in a single row or column range (vector).

Then returns the value at the same position in the second single-row range or single-column range.

If you need to specify a range that contains the value to be found, you can use this form of the LOOKUP function.

Another form of the LOOKUP function automaticallyfinds a value in the first column or row.

SyntaxLOOKUP(lookup_value,lookup_vector,result_vector)
Lookup_value is the value that the function LOOKUP is looking for in the first vector.

lookup_value can be a number, text, a logical value, or a name or reference containing a value.  

Lookup_vector is a range that contains only one row or one column. The value of lookup_vector can be text, number, or logical value.  
Result_vector is a range that contains only one row or one column and must be the same size as lookup_vector.  

DescriptionIf the function LOOKUP cannot find the lookup_value, it searches for the largest value in the lookup_vector that is less than or equal to the lookup_value.
