To return a value in Excel, you can use the = operator to assign a value to a cell. For example, if you want to return the value "Hello" in cell A1, you can use the following formula:

=A1

You can also use the = operator to return the value of a cell in another sheet in the same workbook. For example, if you want to return the value of cell A1 in sheet2, you can use the following formula:

=SHEET2!A1
