Concatenating Multiple Values with Google Sheets
To concatenate text, values from other cells, or functions within a cell, use & to assemble the different elements.
For example, to concatenate the first name, the number of children, and some text, start your formula with a = and then add a & between each element.
The formula here is:
=A2&" has "&B2&" child(ren)"

In this case, to improve the display, it is possible to add functions to handle the singular and plural of "child(ren)" and to display different text if there are no children.
=A2&IF(B2," has "&B2&" child"&IF(B2>1,"ren","")," has no children")

You can also use the CONCATENATE function to replace the &.
