"When working with a large amount of data or solving many calculations, it is sometimes easy to lose track of where certain things are within a worksheet. Scrolling back through your worksheet and hunting for particular sections can lead to spending more time scanning your past calculations than computing new ones. Collapsible Areas can help reduce this wasted time. Collapsible Areas help you organize your data in neat, collapsible sections with clear headings, allowing you to quickly find whatever “section” of your calculations you need."
