I have an Excel spreadsheet with three columns and a few hundred rows. One of the columns is "Date," with the date in the following format: M/D/YYYY H:MM PM EST, which I believe Excel only sees as text, not as actual dates. Unfortunately, the data in the spreadsheet is the output of analytics software that doesn't allow me to customize the output. Because I can't figure out how to either reformat the date as YYYY/MM/DD or get Excel to recognize the dates and sort them accordingly without reformatting, trying to sort by date does not actually sort by date. Here's an example of a few rows' worth of dates incorrectly sorted by Excel: Code: 1/29/2011 2:07 PM EST 1/31/2009 5:21 PM EST 1/6/2012 6:49 PM EST 1/6/2012 8:34 AM EST 10/11/2008 6:34 AM EDT You'll notice that the years are out of order, and after January (month "1") ends, October (month "10") follows instead of February. So it's not even accurately sorting by month. That being said, I want complete date sorting, in full chronological order. Any help is greatly appreciated. Thank you!
