Hi there! It sounds like you're having trouble saving your Excel spreadsheet as a CSV file while keeping the date format as YYYY-MM-DD. Here's what you can do:
- First, make sure that the date column is formatted as YYYY-MM-DD. You mentioned that you've already done this, so great job!
- Next, go to File Save As and choose "CSV (Comma delimited)" as the file type.
- In the "Save As" dialog box, click the "Tools" dropdown menu and select "Web Options."
- In the "Web Options" dialog box, click the "Encoding" tab and select "Unicode (UTF-8)" as the encoding.
- Click "OK" to close the "Web Options" dialog box.
- In the "Save As" dialog box, click "Save" to save the file as a CSV.
- Close the Excel file and open the CSV file in a text editor like Notepad or Editplus.
- Look for the date column and make sure that the dates are formatted as YYYY-MM-DD.
That should do it! By saving the file as Unicode (UTF-8), you're ensuring that the date format is preserved when you open the CSV file again. Let me know if you have any other questions!
