What does the TEXT function do in Excel?

The TEXT function in Excel is specifically designed to convert a numeric value into text in a format that you specify. This is particularly useful when you need to display numbers in a specific way, such as formatting them as currency, percentages, dates, or other numerical formats while ensuring they are treated as text strings.

For example, if you have a number like 1234.56 and you want to display it as currency, the TEXT function allows you to format it as "$1,234.56" while treating it as a text string. This can also be helpful when you want to concatenate numbers with other text, ensuring that the formatting is consistent and displayed correctly in reports or dashboards.

The other choices do not accurately describe the primary function of the TEXT function. While formatting cells to currency or changing the text case are separate functionalities in Excel, they are not what the TEXT function specifically does. Combining multiple text strings relates to functions like CONCATENATE or the ampersand operator, which again is distinct from the role of the TEXT function.
