Vertically Reverse a Range
The SORT function is used to sort a range based on one of the columns in the range.
This function will be used here to vertically reverse a range even when there is no "sorting helper column".
Example of Use
The objective here is to display the same table on the right but with a vertical inversion:

For a column to assist in sorting, it must already be sorted in either ascending or descending order (for example, a column with numbering) to then be sorted in the opposite direction.
In this example, the dates are all unique and in ascending order, so this column can be used as a sorting column.
Simply use the SORT function to perform a descending sort based on this column:
=SORT(A2:B15,A2:A15,0)

Example of Use Without a Sorting Helper Column
There is not always a usable column to perform an inverse sort (and it is rarely desirable to have to add a new column to the table):

In this case, enter the ROW function (with any of the columns in the range as an argument) to sort based on the row number:
=SORT(A2:B15,ROW(A2:A15),0)
