title: How to convert a date in Excel to ISO 8601 format
body: <p>I am trying to save a date format in YYYY-MM-DD, for example, 2014-09-01 as a CSV file, but the format reverts back to the M/D/YYYY format when I do.</p>
  
  <p>I tried converting the date as a string in Excel, but every time I open up the CSV file, it's back to the M/D/YYYY format. I need the ISO&nbsp;8601 date format to be saved in a CSV file. How do I go about doing so?</p>
