LOOKUP
The LOOKUP function searches for a value in a range or array and returns a corresponding value. It returns the first match found. Useful for quickly finding values in a list.
Syntax 🔗
=LOOKUP(lookup_value, lookup_vector, result_vector)
lookup_value | The value you want to find in the lookup_vector. |
lookup_vector | The range or array in which to search for the lookup_value. |
result_vector | The range or array from which the corresponding value will be returned. |
About LOOKUP 🔗
Use the LOOKUP function in Excel to find a specific value in a list or array. It searches through a range to match a specified value and retrieves the corresponding value associated with the first match. This function is useful for extracting relevant data from large lists or tables efficiently. It helps with tasks like data analysis, comparisons, and data manipulation.
Examples 🔗
Suppose you have a list of student names in column A and their corresponding grades in column B. To find the grade of a specific student (e.g., 'John') using the LOOKUP function, you can use the following formula: =LOOKUP('John', A:A, B:B). This will return John's grade based on the first match found in column A, and retrieve the corresponding grade from column B.
Imagine you have a table with product names in column A and their prices in column B. To quickly look up the price of a specific product (e.g., 'Chair') using LOOKUP, you could enter the formula: =LOOKUP('Chair', A2:A10, B2:B10). This formula searches for 'Chair' in the product names and returns the price corresponding to the first match detected.
Notes 🔗
Use the LOOKUP function to find a value in a range. If an exact match for your lookup_value isn't available, LOOKUP will return the closest match that's less than or equal to your lookup_value. Ensure your data is sorted in ascending order for the function to work correctly.
Questions 🔗
If LOOKUP cannot find an exact match to the lookup_value, it will return the closest match in the lookup_vector that is less than or equal to the lookup_value. It is crucial to organize your data appropriately to ensure the accuracy of the returned results.
Can LOOKUP search for values in both rows and columns?Yes, LOOKUP can search for values in both rows and columns. You specify the lookup_vector and result_vector to indicate the ranges or arrays to search and return values from, making it versatile in handling various data structures.
How does LOOKUP handle duplicate values in the lookup_vector?LOOKUP will return the first match it finds in the lookup_vector. If there are duplicate values, it will retrieve the corresponding value for the first occurrence of the value.
