Hi, so I am working on a mac on sheets created on a windows. I need to sort by date, but since all the dates appear like 05/12/2010 (on the left side of the cell) they sort by the first number (the month) instead of the year. To fix this I must edit each cell and hit enter so the date appears like 5/12/10 (on the right side of the cell). But, since I am dealing with THOUSANDS of dates I cannot afford to go in once cell at a time and enter each one. Can I edit all of the dates at once?? Note: the dates are mostly different from each other.
