Yes, there is an Excel formula that can be used to round a date to the end of the month. The formula is called

Code:

EOMONTH

, which stands for "End Of Month". Here are the steps to use this formula:

1. Select the cell where you want to display the rounded date.
2. Type the formula "=
   Code:

   EOMONTH

   (" into the formula bar.
3. Inside the parentheses, type the cell reference or the date that you want to round to the end of the month. For example, if the date you want to round is in cell A1, you would type "=
   Code:

   EOMONTH(A1,0)

   .
4. The "0)" after the comma tells the formula to round to the end of the current month.
5. Press Enter.

The cell will now display the rounded date. For example, if the original date was January 15, 2021, the rounded date will be January 31, 2021. If the original date was February 28, 2021, the rounded date will be February 28, 2021 since it is already the end of the month.
