Text and values in one cell
For example, assume cell A12 contains the value 1435. Enter the following formula into another cell:
The ampersand is a concatenation operator that joins the text with the contents of cell A12.
Applying a number format to the cell containing the formula has no effect, because the cell contains text, not a value. As a work-around, modify the formula to use the TEXT function (the second argument for the TEXT function consists of a standard Excel number-format string).
Here's another example formula that uses the NOW function to display some text along with the current date and time:
="Report printed on "&TEXT(NOW(),"mmmm d, yyyy at h:mm AM/PM")
