Suppose you want to create a grammatically correct sentence from several columns of data for a mass mailing or format dates with text without affecting formulas that use those dates. To combine text with a date or time, use the TEXT function and the & (ampersand) operator.
The example may be easier to understand if you copy it to a blank worksheet.
How to copy an example
Create a blank workbook or worksheet.
Select the example in the Help topic.
Note: Do not select the row or column headers.
Selecting an example from Help
In the worksheet, select cell A1, and press CTRL+V.
To switch between viewing the results and viewing the formulas that return the results, press CTRL+` (grave accent), or on the Formulas tab, in the Formula Auditing group, click the Show Formulas button.
Note: You can copy the number format code used in a cell into a formula. Select the cell, and then on the Home tab, in the Number group, click the arrow, click More, click Custom in the Category list, select the custom format that you want in the Type box, and then copy the contents.
The TEXT function requires two arguments (that is, items between its parentheses). The first argument is a value, such as a date or a number. This value is converted to a text value. The second argument, format_text, is a special string that Excel recognizes and uses to display the converted text value in a format that you specify. In the example above, the date 6/5/10 is converted to text and then is displayed in two different formats: “d-mmm-yyyy” (resulting in 5-Jun-2010) and “mmmm d, yyyy.” (resulting in June 5, 2010).
