What can be achieved by merging cells in a spreadsheet?

Merging cells in a spreadsheet is primarily utilized for enhancing data organization and appearance. When cells are merged, they create a unified area within the spreadsheet that can improve readability and highlight specific information. For instance, merging cells is often used to create a title for a report or to format headers that span multiple columns, making the data underneath more accessible and visually appealing.

This functionality does not directly relate to creating charts, protecting data, or calculating values. Each of those tasks involves different features and functions within a spreadsheet application. Therefore, the ability to merge cells serves mainly the purpose of visually improving the layout and organization of the data presented.
