SMSS Date fields do not display correctly in Excel

I obtained a data set from SMSS as a csv file where I would like to see when an account was created/last accessed. The formattting displays fine in SMSS, but it seems to break when extracted and opened in Excel as shown here.

I have tried the steps listed here but as I do not have access to SMSS myself, I can't try many of the steps.

Is there a way to format the date into a more readable format (ie: DD/MM/YYYY) in Excel using the SMSS extract that I have?

Thank you!
