What command would you use to combine multiple text cells into one in Excel?

The command that correctly combines multiple text cells into one in Excel is TEXTJOIN. This function is designed to join a range of text strings together with a specified delimiter. For example, if you have a list of names in different cells and you want to combine them into one cell with a comma separating each name, TEXTJOIN allows you to specify that delimiter easily while also giving you the option to ignore empty cells.

While CONCATENATE can also be used to combine text from multiple cells, it has limitations such as not allowing the use of a delimiter directly or being limited in how it handles empty cells. MERGE refers to a formatting function that combines the physical space of two or more cells but does not merge the content. AGGREGATE is used for performing various calculations while ignoring errors or hidden rows, rather than combining text.

Therefore, TEXTJOIN is specifically tailored for this purpose and represents the most efficient solution when you need to combine texts from several cells into one.
