- What it is: The function CONCATENATE in Excel is used to join multiple text strings into one single string. It allows you to combine text from different cells or even add specific text within the formula.

- How it is used:

 - To join text from different cells: You can use the CONCATENATE function to merge the contents of two or more cells into one cell.

 - To add specific text: You can include text within the formula to combine it with cell references or other text.

Example of usage:

Suppose you have two cells in Excel:

- A1 contains: "Hello"

- B1 contains: "world!"

You want to combine these two strings into one, separated by a space.

- Excel Code:

=CONCATENATE(A1, " ", B1)

This formula will result in "Hello world!" in another cell where the formula is entered.

- Result:

 - A1: "Hello"

 - B1: "world!"

 - Resulting cell with formula: "Hello world!"
