False. The function "Arrange" is not a standard function in the 'Format' tab in Excel for customizing the sorting order of data. Instead, you typically use the 'Sort' feature, which can be found under the 'Data' tab in the Excel ribbon, to sort data in ascending or descending order. The 'Arrange' term might refer to organizing elements visually within a worksheet, but it does not directly correspond to a specific function for sorting data in Excel.
