What does 'splitting' a worksheet do?

Splitting a worksheet involves dividing it into multiple panes that can be scrolled independently. This feature allows users to view different parts of a large worksheet at the same time, making it easier to compare data or review information without having to scroll back and forth. When a worksheet is split, each pane operates independently in terms of scrolling. This can be particularly useful when working with extensive data sets or when you need to keep one section of the data visible while examining another section. It enhances navigation and usability within the spreadsheet environment.

While merging multiple sheets into one would create a consolidated view of data, it does not facilitate independent scrolling of different sections of the same worksheet, which is the primary function of splitting. Similarly, creating a replica of the worksheet or compressing its size does not relate to the functionality provided by splitting panes. Thus, the correct answer emphasizes the unique capability of viewing and interacting with separate sections of the worksheet simultaneously.
