Sort highlighted data by (date) in first cell - high to low, or low to high

[henryg]

I want a macro to reverse sort any highlighted block of data (rows and columns), no headers, by the cells in the first column - the number of rows and columns is not fixed. The first column will usually be dates, and I would like the reverse of whatever is the current order, low to high or high to low.

I've tried ChatGPT and it successfully did a high to low, but another generated to reverse whatever is there failed.
