Understanding Concatenate and Ampersand (&) in Excel - Their similarities, differences and usage
The question troubles many times why we have both CONCATENATE and AMPERSAND while they serve the same purpose.
Watch this video to understand how both of them are useful
Concatenate and Ampersand (&) both serve the same purpose but it is all about the type of concatenation that you want to do which will decide which one is easier for you. In case of text concatenation, or if you have to just reference the cells; it is good to use Amerpsand because it is quick and easy. When you have to do long calculations along with concatenation, the repeating Ampersand symbol might irritate you. Instead, if you use concatenate function, the only separators are commas and it is easy to use.
Still it is up to you! If you are regularly using Ampersand, you will not find any difficulty in using it in any case or vice-versa.
While the CONCATENATE Function is all nice and proper and well documented, the Ampersand (&) operator is much easier to use in practice.
The Ampersand operator separates the different arguments to be combined in a text string. Much easier to use than typing out CONCATENATE, don’t you think?
In any event, both the CONCATENATE Function and Ampersand Operator return a Text String. Excel will recognize this text string as a Date, but there are problems associated with Dates entered as Text. You can’t change it’s numeric formatting, to name just one.
