I have an Excel column where users must enter dates in the format "yyyy/mm/dd". The cells are formatted as text, not dates, as required by our system. My problem is that sometimes users will enter the numbers as "yyyy-mm-dd" which causes errors in our system because they use dashes instead of slashes.
How can I change their incorrect entry to the correct format automatically or at least have a message pop up telling them they have entered the wrong format? I would prefer to automatically change the dashes to slashes without them having to do anything.
Thanks in advance!
