Which formula would you use to combine the contents of multiple cells into one cell?

The formula used to combine the contents of multiple cells into one cell is CONCATENATE(). This function allows users to take the values or text from different cells and combine them into a single text string. It's particularly useful when you want to create a full name from first and last names stored in different cells or when you need to build a single text string from various pieces of information.

Additionally, CONCATENATE() can take multiple arguments, enabling you to combine numerous cells in one formula easily. For example, if you wanted to combine cells A1, B1, and C1, the formula would be written as =CONCATENATE(A1, B1, C1), resulting in a single string that includes the contents of these cells.

While other options might seem plausible in a different context, they do not specifically serve the purpose of combining cell contents in Excel. For instance, JOIN() is not a standard Excel function, MERGE() refers to merging cells, which affects cell structure rather than content, and LINK() does not exist as an Excel function for this purpose. Thus, CONCATENATE() is the appropriate and correct choice for combining cell contents.
