How can you use the 'Goal Seek' feature?

The 'Goal Seek' feature in Excel is a powerful tool that allows users to determine the necessary input value that will yield a desired outcome for a particular formula. This is particularly useful in scenarios where the desired result is known, but the specific input that will achieve that result is uncertain.

For instance, if you are working with a financial model and you want to determine how much to sell a product to reach a target profit, you can use Goal Seek to adjust the sales figure until the formula calculates the target profit. By setting the formula's output to the desired goal and adjusting the input variable, Goal Seek automatically iterates through potential values for the input until it finds one that achieves the specified goal.

This feature streamlines the process of finding solutions to "what-if" scenarios, making it a fundamental tool for data analysts and decision-makers in various fields.
