I have an excel worksheet with a date column, the format is set to dd-mmm-yyyy but the dates in the columns display as mm/dd/yyyy. If I double click in each individual cell and then move out of that cell the format changes and the dates appear correct. I have 24854 dates I need to change, I can't take time to double click in each cell. Any suggestions? Thanks."
