Format your key to make it visually appealing by adjusting the font, adding borders, or using background colors.

A well-formatted key is more likely to catch the reader’s eye and be used effectively.

Once you complete these steps, your Google Sheets document will have a clear and concise key, making it easier for anyone to understand the data at a glance.
