Description
The LOOKUP function returns a value either from a one-row or one-column range (range: Two or more cells on a sheet. The cells in a range can be adjacent or nonadjacent.) or from an array (array: Used to build single formulas that produce multiple results or that operate on a group of arguments that are arranged in rows and columns. An array range shares a common formula; an array constant is a group of constants used as an argument.). The LOOKUP function has two syntax forms: the vector form and the array form.
| If you want to | Then see | Usage |
|---|---|---|
| Look in a one-row or one-column range (known as a vector) for a value and return a value from the same position in a second one-row or one-column range | Vector form | Use the vector form when you have a large list of values to look up or when the values may change over time. |
| Look in the first row or column of an array for the specified value and return a value from the same position in the last row or column of the array | Array form | Use the array form when you have a small list of values and the values remain constant over time. |
Notes
- You can also use the LOOKUP function as an alternative to the IF function for elaborate tests or tests that exceed the limit for nesting of functions. See the examples in the array form.
- For the LOOKUP function to work correctly, the data being looked up must be sorted in ascending order. If this is not possible, consider using the VLOOKUP, HLOOKUP, or MATCH functions.
