Answer 2

Answer:

When you merge cells, you "physically" merge two or more cells into a single cell. As a result, you have one larger cell that is displayed across multiple rows and/or columns in your worksheet.

When you concatenate cells in Excel, you combine only the contents of those cells. In other words, concatenation in Excel is the process of joining two or more values together. This method is often used to combine a few pieces of text that reside in different cells (technically, these are called text strings or simply strings) or insert a formula-calculated value in the middle of some text.
