Formula generator for LOOKUP function
LOOKUP is a function in Excel that allows you to search for a specific value in a row or column and retrieve the corresponding value from another row or column. It is commonly used for data lookup and retrieval purposes. The function takes three arguments: the search key, the search range or search result array, and an optional result range. The search key is the value you want to find, the search range or search result array is the range of cells where the search key is located, and the result range is the range of cells where the corresponding value should be retrieved from. If the search key is found in the search range, the function returns the corresponding value from the result range. If the search key is not found, the function returns the closest match based on the order of the search range.

LOOKUP formula syntax
The LOOKUP function in Excel is used to search for a value in a range and return a corresponding value from another range. The basic syntax for the LOOKUP function is: =LOOKUP(lookup_value, lookup_range, result_range) - lookup_value: The value you want to find in the lookup_range. - lookup_range: The range of cells where you want to search for the lookup_value. - result_range: The range of cells from which you want to retrieve the corresponding value. The LOOKUP function has two forms: 1. Vector Form: In this form, the lookup_range and result_range must be a single row or single column. The lookup_value should be in the same orientation as the lookup_range. Example: =LOOKUP(A2, A1:A5, B1:B5) 2. Array Form: In this form, both the lookup_range and result_range can be multiple rows and columns. The lookup_value can be in any orientation. Example: =LOOKUP(A2, A1:C5) Note: The LOOKUP function requires the lookup_range to be sorted in ascending order for approximate matches. For exact matches, the lookup_range can be in any order. The LOOKUP function returns the corresponding value from the result_range that matches the lookup_value. If an exact match is not found, it returns the closest match for approximate matches. It's important to note that the LOOKUP function has some limitations and can be replaced with more powerful functions like VLOOKUP or INDEX/MATCH in many cases.

- The LOOKUP function in Excel is used to find a value in a range of cells and return a corresponding value from another range of cells.
- The LOOKUP function searches for a value in the first column or row of a range and returns a value from the same position in a different column or row.
- The LOOKUP function has two required arguments: the lookup_value (the value to search for) and the lookup_vector (the range of cells to search in). It also has an optional third argument: the result_vector (the range of cells to return a value from).
- Yes, the LOOKUP function can handle both exact and approximate matches. By default, it performs an approximate match, but you can specify an exact match by using the optional fourth argument: range_lookup.
- Yes, there are a few things to keep in mind when using the LOOKUP function. It requires the lookup_vector to be sorted in ascending order, and it may return unexpected results if the lookup_value is not found or if there are duplicate values in the lookup_vector.
