Google Sheets’ conditional formatting feature allows users to automatically highlight cells based on certain criteria. In this case, you can use it to highlight cells if the date is before today. This means that any cell with a date that has already passed will be visually distinguished from the rest. This can be useful for managing tasks, schedules, or tracking deadlines. The conditional formatting feature offers a simple and efficient way to organize and prioritize your data, making it easier to stay on top of important dates and events. By setting up the appropriate rules and formatting options, you can customize the highlighting to suit your specific needs. This feature is available to all users of Google Sheets and can be accessed through the “Format” menu.
