I import data from another system that generates a CSV file with dates formatted as MM/DD/YYYY, but my Excel is in Portuguese language, and our standard is DD/MM/YYYY. Even if I try to change the date format in that column to English (USA), nothing happens, and the months and dates continue inverted. Is there any way I can fix it?
If your dates are in same column(s) you may use Text to Columns to them applying proper date format on third step of the wizard. That works column by column. If you have few, better not to open csv but import it into blank file, same conversion could be applied to all columns with dates.
If dates are placed randomly with the file, when change locale setting temporary (Win+R, control international, short date format) and return it back after file conversion.
