Final answer:
The CONCAT function is used for combining text strings, such as merging 'Hello' and 'World!' into 'HelloWorld!'. It does not wrap text, merge cells, or add cell values numerically.
Step-by-step explanation:
The CONCAT function is used in spreadsheet software and programming languages for combining text strings. It is not about wrapping text or cells physically merging, and it does not perform mathematical addition; rather, it is about taking separate pieces of text and combining them into one. For example, if you have 'Hello' in one cell and 'World!' in an adjacent cell, using the CONCAT function would give you 'HelloWorld!' in a new cell.
