Lookup In Google Sheets: A Beginners Guide

Managing data in Google Sheets can be a daunting task, especially when working with large datasets. One of the most powerful tools in Google Sheets is the LOOKUP function, which allows you to search for specific data within a range or table. In this article, we'll take a comprehensive look at the LOOKUP function in Google Sheets, including its syntax, examples, and best practices.

What is the LOOKUP Function in Google Sheets?

The LOOKUP function in Google Sheets is used to search for a value in a range or table and return a corresponding value from another column. It's a powerful tool for data analysis and manipulation, and is commonly used in a variety of applications, including finance, marketing, and operations.

Syntax of the LOOKUP Function

The syntax of the LOOKUP function in Google Sheets is as follows:

LOOKUP(search_key, range, [result_range])

search_key: The value you want to search for in the range.

[result_range]: The range of cells that contains the values you want to return.

For example, if you want to search for the value "Apple" in the range A1:A10 and return the corresponding value from the range B1:B10, the formula would be:

=LOOKUP("Apple", A1:A10, B1:B10)

Fruit	Price
