TEXTJOIN is a Text function in Excel that joins (or concatenates) text strings from two or more cells and separates the combined value using a delimiter.

Modern Excel functions like XLOOKUP, TEXTJOIN, and dynamic arrays offer faster, more versatile, and error-resistant alternatives to outdated tools such as VLOOKUP, CONCAT, and OFFSET.

Adding a text to a cell in Excel using Formula requires use of ampersand operator, CONCAT function, or the LEFT, RIGHT, and LEN functions.
