What function allows a user to combine text strings in Excel?

The function that allows a user to combine text strings in Excel is the CONCATENATE function. This function takes multiple text strings from different cells or directly entered text and combines them into a single string. For example, if you have "Hello" in one cell and "World" in another, using CONCATENATE, you can create "Hello World" as the output.

While TEXTJOIN is a newer function that also allows combining text strings with a delimiter, CONCATENATE has been a long-standing way to achieve similar functionality, particularly in earlier versions of Excel. MERGE typically refers to merging cells rather than combining text strings, and STRINGCOMBINE is not a recognized function in Excel. Thus, the CONCATENATE function remains a fundamental tool for string manipulation within spreadsheets.
