CONCAT(text1, text2, ...)
=CONCAT(A1," ",B1)
The CONCAT function combines two or more strings together. In this example, the CONCAT function combines the value of A1, which is the number 44378, and the value of B1, which is a string, into the result "44378 string".
=A1&" "&B1
This is the same result as the previous example. However, this formula is useful if you want to combine multiple strings together, for example, if you want to concatenate two columns of text for a single result.
=CONCAT("The date is ",TEXT(A1,"mmmm d"))
The CONCAT function can combine a string with a formatted number. In this example, the CONCAT function combines the string "The date is" with the value of A1, which is the number 44378, and formats it as "mmmm d". The result is "The date is July 1".
The CONCATENATE function is a text function in Excel 2016, Excel Mobile, and Excel for the web that joins multiple strings of text into a single string and returns the joined strings. It is being replaced by the CONCAT function.
