What is the primary function of the "Merge Cells" feature in Excel?

The primary function of the "Merge Cells" feature in Excel is to combine multiple cells into a single cell. This capability allows users to create a larger cell that spans across several horizontal or vertical cells in a spreadsheet. Merging cells is often used for formatting purposes, such as creating a centered title across a table or organizing data in a more visually appealing manner. When cells are merged, the content of the upper-left cell is preserved while the content of the other cells is deleted. This makes it a useful tool for enhancing the structure and clarity of data presentations.

In contrast, options that involve changing cell color, splitting cells, or formatting text relate to different functionalities within Excel that serve distinct purposes unrelated to merging cells.
